hey good to have you.
i personally would not advise you to keep smoking weed if i was to say "dont take psychedelics"... you are so young (in that you are still chemically developing) that too much of an external chemical habit, can only create long term imbalances in the later years when the chemical activity begins to slow down again (basically after puberty is mostly set in).
in other words, you are flooding your serotonin receptor sites (located on neurons) with thc during a period of time when lots of new cells are being formed. which means right as these new cells are created, they are automatically conditioned to work at a "baseline" level only when they are stimulated by thc...
concerning the brain in general: the thoughts that you have create "hotspots" in the brain. ie: "familiar" thoughts, "recent" thoughts, are ones that are activated most often. so, following this, a thought = a string of neurons. if your neurons are used to being highly stimulated (for an hour or so), and then crashing (for serveral hours afterwards), how do you think this will affect the conditioning of your thoughts, should you decide that you don't wish to smoke weed any more? (due to price, legality, etc...)
i dont want to give you an "i know what's best" for you speech. that's not my belief, nor my intent at all, if my post comes off that way. in fact, i got into chemical mind expansion at around 16-17. however, that is not to say that i would personally recommend it. i simply believe that one should always be informed if possible. one should always follow their will. what calls to them. in the end that's all you have to face
