Cannabis Products

Product diversification is a key and concerning strategy of today’s cannabis industry. From inhalables to edibles, these are some basics and examples of commonly used products.

These models are based on the best scientific evidence and guided by the principles of public health, social justice, and equity. 

We also provide technical assistance to jurisdictions considering legalizing cannabis. Please contact us for more information.
