Recently I was talking to a bud tender at my local dispensary about chemicals in marijuana. This topic was brought up due to reading an article in high times magazine about high levels of nitrogen and other chemicals being used to increase yield in marijuana. The article has stated that the levels are too high for the human body to break down properly and are there for dangerous to our health. I have a couple questions: Should I be worried? I know I could go organic but what are the risks of using chemical grown marijuana? Am I more at risk than others because I use only a vaporizer? What about bud mold? *off topic but I figured I would kill 2 birds with 1 stone* please get back to me with your accurate responses in your on time, thank you.
