The cannabis industry is growing so quickly that even COVID-19 can’t slow it down. Before the pandemic, the industry amassed $13.6 billion in U.S. legal cannabis sales in 2019 – a figure that is expected to more than double to $30 billion in the next five years, according to New Frontier Data.  In states where cannabis is legal for medical or recreational use, dispensaries have been deemed necessary, essential businesses – especially when it comes to calming stress and anxiety in our ever-changing times.

Cannabis legalization and newly budding dispensaries have expanded across the U.S., which may come with an unfortunate counterpart – a higher incidence of crime. Despite lower prices in states that have legalized cannabis, as compared to states where it is still illegal, theft has run rampant across grow operations, warehouses and, most often, dispensaries.

Dispensaries can be targeted more frequently. Robbers may perceive them as an easy target, because they are businesses that have larger amounts of cash on hand. Many dispensaries only accept cash because payment processors and financial institutions aren’t willing to work with them. This is primarily because cannabis is still deemed an illegal substance under federal law, and the actions of financial institutions are governed by federal, not state, laws. Once the Secure And Fair Enforcement (SAFE) Banking Act is approved, cannabis businesses will be able to work more easily with banks, in turn reducing the amount of cash on site and erasing the dollar signs in opportunistic thieves’ eyes.

However, cash isn’t the only high thieves seek when they break into dispensaries. There’s also the product itself. Protecting it – and providing peace of mind to the facilities’ owners and occupants – is a concern for dispensaries, grow operations and warehouses. Robbers are motivated by the opportunity to make even more fast cash through reselling the product found onsite.

To eliminate such easy targets, security requirements for the cannabis industry are a necessity. They are also involved, complicated, and vary from state to state. A number of security specifications apply between state laws and local ordinances. Inventory must be properly surveilled and managed at all stages of transportation and storage. Any discrepancies in inventory can result in large fines and other penalties. To aid in understanding security compliances, the National Cannabis Industry Association (NCIA), a national trade association, recommends that start-ups obtain attorneys to guide businesses through their state’s laws and regulations.

This is why, especially for new business owners, it is critical to consider the best, most advanced security solutions – especially when it comes to doors and points of egress – that are easily integrated into buildings during the design phase. These solutions protect the products, properties, and people throughout the cannabis supply chain.

Understanding State Security Regulations
While there are no federally recognized security requirements for the cannabis industry, there are similar requirements across all states that have legalized cannabis, including:

  • Maintaining strict access control throughout the facility – this is especially important for grow operations and warehouses
  • Functional alarm systems
  • Documented standard operating procedures
  • Video surveillance systems – many states mandate very precise requirements, such as length of storage time and even video resolution specifications
  • Notifying appropriate regulatory agencies immediately or within a strict timeframe after a security incident or theft
  • Securing all records and record storage

While these are common, state-mandated security requirements, it is critically important to know and understand all rules, regulations, and laws concerning the industry within the business’s specific state. Making sure the business is compliant with all aspects of state laws for security and preventing violations, including the hefty financial penalties that can accompany them, is key.

States require cannabis facilities to implement sophisticated security features for several reasons. One of the most obvious is the fact that the industry supplies a high-value product and is a cash-intensive business. Integrating security features into the building can be a challenging task for architects and designers. To help tackle these challenges, manufacturers have introduced products to the cannabis industry, creating easier, more effective and aesthetically pleasing security solutions.

Integrated Designs For High Level Security
Security shouldn’t be a constraint when considering design aesthetics. Certain elements can be discretely tucked away, including cameras and security doors by way of specifying a concealed rolling door, conveniently disguised in the ceiling during operating hours. These doors can even close under alarm eliminating the need for manual intervention. Other security measures, such as bullet resistant glass, are hidden in plain sight.

Rolling doors like this one can be conveniently disguised in the ceiling during operating hours.

Untrustworthy employees, smash-and-grab thefts or meticulously planned heists mean secure building design is of the utmost importance. In order to have the most effective security, there needs to be design vision – a clear intent for incorporating advanced security into the facility, whether visible or not.

Suggested security measures include video surveillance around the outdoor perimeter of the property as well as inside the facility. Physical barriers, such as specialized entrance locking systems – including fingerprint-scanning biometric technology – and security doors that may also include intrusion detection and automatic closure systems are recommended. All systems may be paired with 24/7 visual monitoring by security personnel.

Many state regulations also require restricted access to specific areas within dispensaries, grow operations and warehouses, with employee names and activities logged for reference. These necessary measures aid in inventory monitoring and control, further reducing the likelihood of internal theft.

When specifying building security, it’s important for architects to consider what type of building they are designing. There are differences in providing security for dispensaries versus warehouses and grow operations. Dispensaries and storefronts are frequently out in the open and in locations that are well-known to consumers. Warehouses and grow operations are usually tucked out of the way, rarely publicized, and less noticeable.

Rolling Grilles And Doors Deter Dispensary Theft
With a high-value product and cash on hand, dispensaries in particular have unique security challenges. And because they are retail businesses, egress and fire codes must be strictly adhered to, in addition to special security regulations.

Rolling grilles can be an effective deterrent against dispensary theft

In light of this, security doors require special consideration. They are necessary to provide secure protection against theft but shouldn’t distract from the architectural vision of the building or interior design.

Rolling security grilles are the ideal solution to protect the counter inside the dispensary and may also be ideal for the front of the store. They fit in small headspaces where there is limited ceiling room and can be easily concealed when not in use.

Even heavy-duty rolling doors used to protect the glass storefront of the dispensary and prevent intruders from entering the building’s dock area can be hidden when not in use. If building code allows, architects may specify a rolling door that coils up into the door’s header, residing behind an exterior soffit. These robust security doors’ lift-resistant bottom bars also can be obscured from sight.

Heavy-duty security doors at the front of the dispensary block sight access and provide a visual deterrent. They give the building a secured look when in use, but heavy-duty rolling doors don’t need to be imposing to customers during the dispensary’s operating hours.

Robust Visible Protection For Grow Operations And Warehouses
Grow operations and warehouses usually opt for more visible security doors to deter criminal activity. They also have different design considerations because of building layout and production needs. For instance, larger grow operations house plants and supplies which require heavy equipment to move throughout the facilities.

A heavy duty steel rolling grille

Heavy duty rolling security doors can be made with up to 12-gauge steel with interlocking slats and tamper resistant fasteners – making them stronger than standard garage doors. They provide high-end security at loading docks and limit access to restricted areas inside.

Rolling doors can also be used to block employee access to off-limits areas common in grow operations and warehouses. Because they are heavily reliant on utilities and infrastructure, such as water mains and humidity and temperature controls, warehouses and grow operations are ideal applications for rolling doors. If unauthorized personnel with ill intentions access these utility areas, it could spell disaster with ruined crops and damaged or unsafe products – turning into substantial financial losses. From a design standpoint, these doors do not need to be concealed. In fact, their visibility signals restricted access areas and hints at the security measures taken to protect these facilities.

Enhanced Security Features
Whether designing a dispensary, a grow operation facility, or a warehouse, rolling doors may be paired with automatic protection features to enhance the building’s security and help workers feel safe. These automatic closing systems allow the security doors to be immediately activated by a building alarm or the push of a panic button in emergency situations. The doors also feature advanced locking systems – some of which are hidden in non-traditional locations – providing further tamper resistance.

Some rolling door manufacturers offer in-house architectural design groups to guide architects and designers in choosing the ideal security doors. These groups can address and solve any design dilemmas that arise during the project. Every rolling door is built to a specific opening, making each product unique to that area of the project. Because of this customization, manufacturers can meet virtually any specification.

Meeting Insurance Requirements
Selecting the correct rolling door along with other advanced security features aids in meeting insurance requirements. Each insurance company has individual minimum-security conditions in its policy. Many insurance companies will not provide theft insurance if cannabis businesses do not have adequate security or cannot demonstrate they have it.

Planning Leads To Integrated Protection
The technical and legal aspects of securing dispensaries, grow operations, and warehouses can be overwhelming and, at times, confusing. Legal counsel, state agencies, industry associations, and manufacturers encourage new cannabis businesses to use them as resources as they unravel the nuances of the industry’s security regulations.

By combining robust security features such as video surveillance, proper access controls, rolling doors or grilles and automatic closure systems, cannabis facilities can meet state and insurance requirements and deter theft. With thoughtful design consideration and planning, these security features also have the capabilities to seamlessly blend with interior and exterior design aesthetics.

Multi-Element Analysis Using ICP-MS: A Look at Heavy Metals Testing

Across the country and across the world, governments that legalize cannabis implement increasingly rigorous requirements for laboratory testing. Helping to protect patients and consumers from contaminants, these requirements involve a slew of lab tests, including quantifying the levels of microbial contaminants, pathogens, mold and heavy metals.

Cannabis and hemp have a unique ability to accumulate elements found in soil, which is why these plants can be used as effective tools for bioremediation. Because cannabis plants have the ability to absorb potentially toxic and dangerous elements found in the soil they grow in, lab testing regulations often include the requirement for heavy metals testing, such as Cadmium, Lead, Mercury, Arsenic and others.

In addition to legal cannabis markets across the country, the USDA announced the establishment of the U.S. Domestic Hemp Production Program, following the enactment of the 2018 Farm Bill, essentially legalizing hemp. This announcement comes with information for hemp testing labs, including testing and sampling guidelines. While the information available on the USDA’s website only touches on testing for THC, required to be no greater than 0.3% dry weight concentration, more testing guidelines in the future are sure to include a discussion of heavy metals testing.

Table 1. ICP-MS operating conditions (shaded parameters were automatically optimized during start up for the HMI conditions).

In an application note produced by Agilent Technologies, Inc., the Agilent 7800 ICP-MS was used to analyze 25 elements in a variety of cannabis and hemp-derived products. The study was conducted using that Agilent 7800 ICP-MS, which includes Agilent’s proprietary High Matrix Introduction (HMI) system. The analysis was automated  by using the Agilent SPS 4 autosampler.

Instrumentation

The instrument operating conditions can be found in Table 1. In this study, the HMI dilution factor was 4x and the analytes were all acquired in the Helium collision mode. Using this methodology, the Helium collision mode consistently reduces or completely eliminates all common polyatomic interferences using kinetic energy discrimination (KED).

Table 2. Parameters for microwave digestion.

As a comparison, Arsenic and Selenium were also acquired via the MassHunter Software using half-mass correction, which corrects for overlaps due to doubly charged rare earth elements. This software also collects semiquantitative or screening data across the entire mass region, called Quick Scan, showing data for elements that may not be present in the original calibration standards.

SRMs and Samples

Standard reference materials (SRMs) analyzed from the National Institute of Standards and Technology (NIST) were used to verify the sample prep digestion process. Those included NIST 1547 Peach Leaves, NIST 1573a Tomato Leaves and NIST 1575 Pine Needles. NIST 1640a Natural Water was also used to verify the calibration.

Figure 1. Calibration curves for As, Cd, Pb, and Hg.

Samples used in the study include cannabis flower, cannabis tablets, a cannabidiol (CBD) tincture, chewable candies and hemp-derived cream.

Sample Preparation

Calibration standards were prepared using a mix of 1% HNO3 and 0.5% HCl. Sodium, Magnesium, Potassium, Calcium and Iron were calibrated from 0.5 to 10 ppm. Mercury was calibrated from 0.05 to 2 ppb. All the other elements were calibrated from 0.5 to 100 ppb.

Table 3. Calibration summary data acquired in He mode. Data for As and Se in shaded cells was obtained using half mass correction tuning.

After weighing the samples (roughly 0.15 g of cannabis plant and between 0.3 to 0.5 g of cannabis product) into quartz vessels, 4 mL HNO3 and 1 mL HCl were added and the samples were microwave digested using the program found in Table 2.

HCI was included to ensure the stability of Mercury and Silver in solution. They diluted the digested samples in the same acid mix as the standards. SRMs were prepared using the same method to verify sample digestion and to confirm the recovery of analytes.

Four samples were prepared in triplicate and fortified with the Agilent Environmental Mix Spike solution prior to the analysis. All samples, spikes and SRMs were diluted 5x before testing to reduce the acid concentration.

Calibration

Table 4. ICV and CCV recovery tests. Data for As and Se in shaded cells was obtained using half mass correction tuning.

The calibration curves for Arsenic, Cadmium, Lead and Mercury can be found in Figure 1 and a summary of the calibration data is in Table 3. For quality control, the SRM NIST 1645a Natural Water was used for the initial calibration verification standard.  Recoveries found in Table 4 are for all the certified elements present in SRM NIST 1640a. The mean recoveries and concentration range can also be found in Table 4. All the continuing calibration solution recoveries were within 10% of the expected value.

Internal Standard Stability

Figure 2 highlights the ISTD signal stability for the sequence of 58 samples analyzed over roughly four hours. The recoveries for all samples were well within 20 % of the value in the initial calibration standard.

Results

In Table 5, you’ll find that three SRMs were tested to verify the digestion process. The mean results for most elements agreed with the certified concentrations, however the results for Arsenic in NIST 1547 and Selenium in both NIST 1547 and 1573a did not show good agreement due to interreferences formed from the presence of doubly-charged ions

Table 5. Mean concentrations (ppm) of three repeat measurements of three SRMs, including certified element concentrations, where appropriate, and % recovery.

Some plant materials can contain high levels of rare earth elements, which have low second ionization potentials, so they tend to form doubly-charged ions. As the quadrupole Mass Spec separates ions based on their mass-to-charge ratio, the doubly-charged ions appear at half of their true mass. Because of that, a handful of those doubly-charged ions caused overlaps leading to bias in the results for Arsenic and Selenium in samples that have high levels of rare earth elements. Using half mass correction, the ICP-MS corrects for these interferences, which can be automatically set up in the MassHunter software. The shaded cells in Table 5 highlight the half mass corrected results for Arsenic and Selenium, demonstrating recoveries in agreement with the certified concentrations.

In Table 6, you’ll find the quantitative results for cannabis tablets and the CBD tincture. Although the concentrations of Arsenic, Cadmium, Lead and Cobalt are well below current regulations’ maximum levels, they do show up relatively high in the cannabis tablets sample. Both Lead and Cadmium also had notably higher levels in the CBD tincture as well.

Table 6. Quantitative data for two cannabis-related products and two cannabis samples plus mean spike recovery results. All units ppb apart from major elements, which are reported as ppm.

A spike recovery test was utilized to check the accuracy of the method for sample analysis. The spike results are in Table 6.

Using the 7800 ICP-MS instrument and the High Matrix Introduction system, labs can routinely analyze samples that contain high and very variable matrix levels. Using the automated HMI system, labs can reduce the need to manually handle samples, which can reduce the potential for contamination during sample prep. The MassHunter Quick Scan function shows a complete analysis of the heavy metals in the sample, including data reported for elements not included in the calibration standards.

The half mass correction for Arsenic and Selenium allows a lab to accurately determine the correct concentrations. The study showed the validity of the microwave sample prep method with good recovery results for the SRMs. Using the Agilent 7800 ICP-MS in a cannabis or hemp testing lab can be an effective and efficient way to test cannabis products for heavy metals. This test can be used in various stages of the supply chain as a tool for quality controls in the cannabis and hemp markets.
