Cannabis/Weed Packaging: How to Stay Compliant

by Aly Payne,

State cannabis regulators dedicate the majority of their time and effort to a single goal: preventing the diversion of cannabis products to minors and the black market. Weed labeling and packaging compliance plays a major role in meeting this end.

While the goal of preventing minors from consuming cannabis seems like a simple one, it requires regulators to navigate a complex legal landscape. Every state has its own laws, and most states regularly update, change, and revise their regulations.

This is most evident in the context of packaging and labeling. For instance, California implemented new packaging regulations for the cannabis industry in January 2020 and left manufacturers with virtually no grace period for adopting the new laws – and that is just one state.

Cannabis manufacturers who want to do business in more than one state must maintain compliance with multiple regulatory bodies in parallel. This can quickly become an overwhelming task if two or more states change their rules during the same time period of time.

Why Cannabis Packaging Matters

Most of the earliest cannabis packaging laws treated cannabis like any prescription drug. Many medical cannabis dispensaries continue to use the nondescript cylindrical pill bottles favored by pharmacies – sometimes with a telltale green hue replacing the pharmacy-standard orange.

These pill bottles came about as a result of the 1970 Poison Prevention Packaging Act and proved successful at reducing the number of children who suffered drug-related accidents. However, while these bottles function well for prescription pills, they don’t do a very good job at preventing cannabis ingestion as they are transparent.

As a result, many states adopted regulations requiring dispensaries to place cannabis purchases in opaque, child-resistant pouches or bags. This led to a new problem – consumers tend to remove their cannabis purchases from the child-resistant dispensary pouch and place them in a more accessible location at home.

This has led some manufacturers to rethink their strategy for maintaining weed packaging compliance. Instead of treating regulation like an unwanted cost, they are re-aligning their packaging processes to offer safe, attractive product containers that meet stringent regulatory needs.

Both compliance and marketing play a major role in this decision. Customized packaging allows cannabis product manufacturers to give themselves branding space in an industry where effective marketing is infamously difficult.

Aesthetics, Functionality, and Compliance

Cannabis manufacturers need to understand that product packaging can be both child-resistant and attractively designed. The design element is important because it generates branding opportunities and helps ensure compliance at the consumer level, which in turn prevents regulators from coming up with even stricter rules to follow in the future.

Instead of repurposing awkward boxes, glass jars, and pharmaceutical containers, the most forward-thinking brands of today’s cannabis market are creating unique packaging solutions designed to meet multiple goals at once. Well-designed weed packaging can play a strategic role in the success of an entire enterprise if it meets its goals in the following areas:

  • Compliance. Regulatory compliance will always be a top concern for cannabis manufacturers. No manufacturer can take a solution to market unless it meets – or even better, exceeds – state rules.
  • Efficiency. Manufacturers have multiple economic incentives to reduce waste when packaging cannabis products. The use of easily obtainable, highly reusable materials can be a long-term net gain if properly implemented.
  • Cost-Reduction. While some cannabis products may benefit from luxury branding to attract higher-end customers, most manufacturers want to identify compliant, efficient, low-cost solutions for marijuana product packaging.
  • Environmental Sustainability. Some cannabis packaging companies are developing sustainable, common-sense solutions by using hemp to package cannabis products. Paper and reclaimed plastic can also make a significant difference in a manufacturer’s environmental footprint and lead to valuable branding opportunities.
  • Aesthetics. Cannabis users tend to think of themselves as being part of a unique culture. Aesthetically pleasing packaging that reinforces this cultural identity can lead to a product outperforming equally valuable options at the dispensary cash register.

Packaging Examples for Specific Product Types

Finding the perfect solution for your cannabis company’s packaging needs requires taking a close look at the regulations of the states you wish to operate in. No one can offer a one-size-fits-all solution, but the following examples should inspire manufacturers to find one that is appropriate for their unique situation and goals.

  • Cannabis Flower Packaging. Customized smell-proof containers can make a remarkable impact on the marketing success of cannabis flower. Some cultivators are using child-resistant containers made of customized wood, glass, or even metal to distinguish their products from the competition. These containers must also offer ideal moisture and lighting conditions to protect the product’s shelf life.
  • Vaporizer and Extract Packaging. Vape and extract packaging solutions offer significantly greater opportunities for branding and design innovation. Experiential packaging is becoming a greater part of the vape consumer’s journey, offering brands new ways to communicate with their customers, often through the lens of luxury packaging and quality.
  • Edibles Packaging. The edibles industry is one of the most important when it comes to childproof packaging. Children can be remarkably resourceful in obtaining what they think is chocolate or candy, and brands like CRATIV are engineering solutions that serve to minimize the risk of accidental ingestion.
  • Concentrate Packaging. Many concentrate packaging providers are taking their aesthetic cues from the cosmetics industry. Custom-molded, childproof containers are a must when packaging products like hash, wax, crumble, and shatter, which are difficult to manage in ordinary pharmaceutical containers or bags.

State-by-State Packaging and Labeling Law Overview

Packaging laws vary widely by state and tend to differ between flower, vaporizer, edible, and concentrate products. The following list of packaging and labeling regulations illustrates some of the differences in weed packaging laws between US states:

Collaboration and Branding Opportunities

One of the most important things for cannabis manufacturers to realize is that they aren’t in this alone. Cannabis packaging companies are working with product developers, cannabis industry designers, and compliance consultants to offer solutions that maximize the viability of their products across state markets.

Manufacturers who are serious about opening up markets across multiple states will need to rely on customizable packaging and flexible delivery options. Third-party vendors often offer the most cost-effective options for obtaining these results in a scalable way while minimizing risk.
