Is your marijuana safe? Lack of data makes it hard to know in the long term
Briefly

As states like Colorado legalize marijuana, the challenge of ensuring product safety emerges, particularly concerning pesticides and contaminants. Jeff Raber, CEO of The Werc Shop, emphasizes that what's harmful varies per individual based on factors like size and usage frequency. Colorado mandates strict testing for harmful substances, but existing data is scarce, complicating regulations. A past study showed pesticides could reach users through smoking methods. Recently, Colorado updated its pesticide regulations, adopting frameworks from Canadian standards, reflecting the collaborative effort to enhance safety in the marijuana industry.
Safe' is a funny word, both because what is harmful to one person may not be for another, and because people vary in their risk tolerance.
Regulators had to work with limited existing information on the possible risks of pesticides and contaminants in marijuana, because few, if any, studies have examined what levels might be safe.
A 2013 study that Raber co-authored found that significant amounts of pesticides could pass through water pipes or glass pipes to the user.
Colorado based its updated 2023 pesticide regulations on rules in place in Canada, after a group of researchers and stakeholders considered various sets of standards.
