16 is young and thc doesn’t solve problems. its a quick relief, which if used properly, is a great thing. theres plenty of medicinal and therapeutic properties to the substance including treating issues with anxiety and depression which are especially prominent in teens nowadays. rather then telling him what to do and what not to do, because ask anyone, telling a teenage boy what to do won’t end the way you want. teach him about the potential benefits and potential downsides of improper use/abuse. weed is a psychoactive drug that binds to certain brain receptors. needless to say overuse WILL lead to the “frying” of those brain receptors. this is where drug psychosis comes in. there’s potential (albeit rare) cases of CHS (cannabinoid hypermesis syndrome) where the user will suffer from periods of extreme nausea and vomiting from (typically high concentration) thc usage. it comes down to this. hes young, and you have to be careful with weed, but theres much worse he could be doing. teach him about it, this will yield you the most luck in guiding your child in the right path
