It’s important to know and trust the source of anything that you consume in your body. It’s easy to simply eat food wherever it’s available without thinking twice about how it was prepared. I used to ask for hot dogs everywhere my parents took me as a kid, including when we visited the hardware store. They have a food truck out there most days and hot dogs are their main attraction. You would think that of all prepared food, hot dogs would be the safest but it didn’t stop me from getting food poisoning on half a dozen instances over the years from hot dogs alone. If I want a hot dog, I’ll buy a pack at the store and will cook them at home where I know that I’m handling my food properly. But people do this with drugs too, especially if they are sourcing things like marijuana from the black market. I had a few friends in college who got bad batches of LSD from a new dealer that neither of them had met before. I think it was actually this rare drug called DOM because the experience for them lasted three days until the drug finally wore off. That made me extremely hesitant to buy any drugs on the black market, in particular marijuana. I get all of my marijuana products from the medical cannabis dispensary, even CBD. Every cannabis product at the medical dispensary is lab tested for purity. Random CBD products at gas stations and in web stores are not necessarily lab tested to make sure they don’t have residual solvents or other impurities that could hurt someone with long term exposure.
