For commercial cannabis growers, consistent crop yields are vital to maintaining product profitability, as well as durable profitability. Since cannabis thrives under certain conditions, the more control a cultivator has over those conditions, the easier consistent harvests become.

While factors like humidity, light exposure and water may be easy enough to control in any indoor environment, other influential factors can be more difficult to control, such as mold or other contaminants. Growing in a controlled cleanroom environment ensures healthy, high-quality cannabis by mitigating some harder-to-control threats. For these reasons, growing cannabis in a cleanroom environment is rapidly becoming the gold standard in the industry.

A Closer Look at the Cleanroom Environment

A cleanroom facility is a specially designed room or modular addition designed to support a tightly controlled grow environment for crops. The design of the cleanroom relies on several design features to deter issues with pollutants, such as insects, mold, airborne microbes and dust. Even though cleanroom environments are often affiliated with cultivating certain types of crops, these facilities are also valuable in other industries, such as medicine, biology and pharmaceuticals.

Cleanrooms can be conservatively sized or massive. They can be configured to accommodate different processes, and they can be built to suit a specific grower’s preferences. However, several features are key, such as:

  • Cleanroom-rated HEPA (high-efficiency particulate arrestor) filtration
  • Contamination control mats
  • Positive-pressure airflow systems
  • Double-door air chambers at entry points
  • Moisture-resistant wall panels
control the room environment
Preventing contamination can save a business from extremely costly recalls.

One fundamental requirement of a cleanroom is to control the introduction of contaminants into the space. Contaminants can be carried in on the people who visit the space. Therefore, cleanroom implementation must come along with strict protocols when it comes to employee entry into the room. For example, air showers, special gowns, masks and other measures may be required. 

The Benefits of Cleanroom Environments for Cultivators

On the surface level, cleanrooms make it possible to achieve a well-controlled environment for cannabis cultivation. However, while this is undeniably important in terms of consistent crop yields and profitability, cleanrooms pose a number of broader advantages for cultivators and end customers.

Meet Laboratory Testing Guidelines and Protocols

For now, states create product testing regulations for cannabis. Most states that have legalized medical or adult use cannabis have created protocols for lab-testing products for pesticides and microbes. When batches of cannabis product do not meet state lab-testing standards, the product can be recalled or destroyed. In 2016, Steep Hill published an alarming study that showed they detected pesticides in roughly 70% of the samples they received and up to one third of all samples would have failed to meet regulatory standards. Cleanrooms reduce a grower’s reliance on pesticides.

Negate the Risk of Fungal Contamination

Cleanrooms negate the risk of fungal contamination through proper ventilation, particulate control and positive pressure.

Cannabis is prone to certain types of fungal spores that can cause severe illness in end customers. For example, Aspergillus mold spores are common in cannabis and can lead to cases of chronic pulmonary aspergillosis. In large doses, Aspergillus mold spores may even cause liver failure due to the carcinogenic mycotoxins the spores produce in the body. Cleanrooms negate the risk of fungal contamination through proper ventilation, particulate control and positive pressure. 

Create a Safer Work Environment for Employees

Employees who work in cultivation facilities in the cannabis industry face various occupational hazards. Many of these hazards are related to being in contact with fungicides, mold spores and chemical fertilizers. The exposure can result in issues such as allergic reactions, respiratory irritation and other physical threats. Cleanrooms and how they function can deter many of these risks. For example, the lack of need for fungicide use automatically lowers the risks due to lacking exposure. Further, because protective gear is required to maintain the integrity of the cleanroom, there is less of a chance an employee’s skin or respiratory system is exposed to irritants.

Cleanrooms: The Potential Future of Cannabis Cultivation

As cannabis becomes a more robust industry and regulations become more clearly defined, growing standards are bound to change. As speculations of national regulations veer closer to reality, growing cannabis industrially may even mean required cultivation facility upgrades. Cleanroom environments give growers firm control over the health of their crops while ensuring clean products for customers. Therefore, these innovative and health-forward implementations could easily become the norm in the cannabis industry in the future.

What’s Happening on Capitol Hill? Cannabis Reform Proposals and the 115th Congress

By Brian Blumenfeld, J.D., M.A.

As CIJ readers are probably aware, last month Congress passed the Consolidated Appropriations Act of 2017—the annual budget, in other words. Lying within this 1,665-page document is Section 537, which for one year restricts the Department of Justice from using any funds to prevent states from implementing their medical cannabis laws. Medical cannabis businesses and patients can take some solace in this restriction. Last summer, the influential U.S. Court of Appeals for the Ninth Circuit, sitting in San Francisco, confirmed that this appropriations rider prevents federal prosecutors from bringing suit against medical cannabis businesses and users operating in compliance with state law. Two problems remain glaring, however: one, the protection only applies to medical cannabis activity, not recreational; and two, it is only guaranteed to last for one fiscal year.

To be sure, for the 115th Congress to address the profusion of issues emerging from the nationwide legalization movement, they must do something more. Various reform proposals have in fact been introduced during the current congressional session, and in order to fully digest where they stand and what they have the potential to accomplish, it will help to make sure that we know how they fit within federal legislative procedure.

Catching Up to Speed with the Legislative Process 

How A Bill Becomes A Law

Whenever confronting a question about government and politics, it is never a bad idea to start at the source of authority. In America, that source is of course the Constitution, and in Article 1, Section 5, Clause 2, We The People have given to Congress the power to “determine the rules of its proceedings”.  When we remember back to the School House Rock cartoon for How A Bill Becomes A Law, the majority of political maneuvering behind the basic process taught in the cartoon actually happens according to these ‘rules’ or ‘resolutions’. In fact, at the beginning of each new Congress (every two years) each chamber, and each committee and subcommittee within each chamber, votes on the rules that will govern how they are to go about their legislative business. Traditionally, the rules from the previous Congress are carried over by this vote with only minor tweaks. On top of that, both parties in each chamber have their own internal rules and procedures for setting their policy agenda, directing political strategy, and determining which members will be nominated to certain leadership positions and committee posts. Playing the game of politics according to this layer cake of rules is a necessary part of the work of a legislator, and is often as important a factor in how our country is actually governed as is who wins election to office and what substantive provisions are formally enacted into law. So for the purposes of understanding federal cannabis reform, let’s take a quick look into the procedural status of the relevant legislation and who is in a position to influence what happens to it; then, when reviewing the policies they stand to codify, we will also understand the legislative landscape they must navigate.

A good place to start is February 16, 2017 when Republican Congressmen Dana Rohrabacher (R-CA) and Don Young (R-AK) along with Democratic Congressmen Earl Blumenaur (D-OR) and Jared Polis (D-CO) launched the Congressional Cannabis Caucus. Under House and Senate rules, such a caucus must formally register with the House Committee on Administration as a Congressional Member Organization (CMO), disclosing its officers and members and declaring its purpose. These CMOs are sometimes referred to by different names: caucuses, conferences, coalitions, task forces, etc. The best known of these are the House and Senate Democratic Caucuses and the House and Senate Republican Conferences. By setting party policy, driving legislative strategy, promoting party cohesion and rewarding party loyalty, these largest of CMOs dominate partisan activity on Capitol Hill. Smaller CMOs, on the other hand, advance only specific interests and often cross the partisan divide. The Cannabis Caucus, for instance, was formed to catalyze a federal response to the nationwide legalization movement, and its “Path to Marijuana Reform” is a large part of the spate of bills that have been dropped into the congressional hopper over the past six months.

All in all there are twenty cannabis reform bills currently pending in Congress. In the House, all but two of the fourteen bills there have been referred to either the Energy & Commerce Committee or the Judiciary Committee, and all but one of the six in the Senate have been referred to either the Finance or Judiciary Committees.

A Note on Committees & Procedure

Under House and Senate rules, bills are referred to committees by matching the former’s subject matter to the latter’s jurisdiction. In the House, the Speaker may attach time limits for committee action, refer a bill or portions of a bill to multiple committees and determine the sequence in which they are to be considered. The Speaker may also convene an ad hoc committee to consider a bill, and “make such other provision as may be considered appropriate.” As can be gleaned, the Speakership holds substantial procedural powers, and is in fact the only congressional leadership position created by the Constitution. The Senate’s counterpart, the majority leader, has in comparison less discretion in moving along legislative business.

At the next step, both the House and Senate grant each committee the authority to make their own rules on how they are to consider bills. Once referred, committee chairs generally decide to further refer a bill to a subcommittee, hold hearings, subpoena evidence and witnesses, call ‘markup’ sessions to propose and debate amendments, and finally to schedule a vote to report bills back to the chamber floor. If a committee chair wishes to kill a bill, these procedural powers provide wide, though not absolute, authority to do so. Jockeying for a chairmanship is therefore big game in the life of a legislator. Ultimately, members are nominated and elected to their respective committees and chairs according to the rules of their parties’ caucus or conference, and upon a vote of approval on the floor. Seniority is only one factor in these votes, and so because nothing is predetermined, these intraparty contests can explain a great deal about member behavior.

With that background to help triangulate Capitol Hill politics, we should now be better equipped to look into the cannabis bills pending before the 115th Congress, the committees to which they have been referred, and their procedural status. Stay tuned for the next article in this series when we will begin our bill-by-bill review.
