I never did drugs but still i am sure the THC Marijuana part might be wrong in many cases, but the most someone else has mentioned already so i will only mention facts i have been observing of my Friends or comrades as they smoked Marijuana occasionally, they get increased mood, also giggle a lot and so far they got very talkative but also calm and relaxed, so far only one of them did mention hallucinations, flashbacks, persons that are not there etc. while the other one was overwhelmed by its effects like lost of timeflow, he pretty much was stoned and lost in his thoughts, kinda losing focus of reality itself kinda like his mind was open far and wide but got overwhelmed by it.(he kinda ate too much brownies)
The Fact that you forgot to mention one of the most harmful legal drugs in your simulation is kinda lame, Alcohol is in quite a lot cases way more harmful and destructive than THC ever can be, yes even the long term effects are way worse, i know that because i actually have lost some friends or relatives because of the long term effects of Alcohol, they got worse and worse until they may have overdone it thus die from it. Their Health absolutely destroyed, you know in all my lifetime with quite some weed loving friends i didnt ever hear anything worse that comes even close to the risk of alcoholism, please do your research and update your Simulation as its educative value should never show only one side of its "Truth"
