The mental and physical effects of Marijuana vary greatly from person to person. I know people that absolutely can not function at all when high even when building up a stronger tolerance as well as people who are daily smokers that you can't even tell are high because that's how regularly they get high and have no noticeable side effects cognitively. I believe that Marijuana enhances conditions that people are prone to that pertain to its effects. For example, if you're normally a lazy person, smoking regularly or excessively will cause you to be a lot more lazy than you are used to. If you are forgetful, then too much consumption will cause you to be a lot more forgetful. I even have a friend who I believe was prone to schizophrenia who started smoking A LOT and along with other environmental factors caused early stage symptoms of schizophrenia to surface. Personally, I smoke concentrates on a near daily basis and cut down when I feel I've been smoking too much because too much of anything is not good for you. Marijuana isn't for everyone but it's medical uses can't be denied and I'm happy I can smoke without serious problems health wise. (Also if you're underage and reading this, my advice to you is to not smoke at all. Like i said, it's not for everyone and it can be an expensive habit) I know I wrote a whole essay on this but I'm bored at work and waiting to go home to catch the boxing match and play some Destiny lol. Peace out
