It’s best to keep foreign or harmful synthetic chemicals out of your body if you can actually do it.
There are especially strict directions for lab testing with prescription medications so that sick people aren’t inadvertently consuming chemical solvents for instance when they need to take their medication.
Even the presence of safety seals on over-the-counter product is a completely necessary thing, as the people I was with and I learned in 1982 with the Chicago Tylenol murders that left 7 people dead from Tylenol-branded acetominophen pills that had been laced with potassium cyanide. No one was ever busted for the actual murders that occurred, however it’s actually believed that the poison was added to bottles that were resting on store shelves, long after they had left the factory. But there are quite a few ways that we expose ourselves to potentially harmful chemicals. People who enjoy tobacco or cannabis products have to use some form of fire to burn the plant material. Some people simply carry butane lighters, although I don’t prefer inhaling the gas every single time I want to consume the plant. When I started using hemp wicks to smoke bowls of pot, I never looked back. My medical marijuana tastes so much better and I don’t have to be bothered about inhaling butane either. These little hemp wicks aren’t all that valuable either, especially if you get them from a supplier that makes them by hand. The core is hemp cord and it’s basically coated in beeswax so it stays lit. These wicks were around back when I was in school, although I never tried them until more recent times. I’m all about consuming as few synthetic chemicals as I can actually do, especially when it comes to things I’m heating and inhaling into my crucial lungs.
