your asking about MJ ruining your life, IMO its not the MJ but the head its going into. your actions and emotions are created by the big melon sitting on your shoulders. so the problem lies in the head not what your putting into it.
the fact that ones own mental state has everything to do with addictions being left out leads me to believe that one has yet to deal with addictions or understand addiction or mental defects. how can reading a article and no hands on experience be enough to form what is being presented as fact for all. hell years of medical research had yet to provide a cure. you can look at a person and tell all are different in many ways. this is simple observation. unless you are a neurosurgeon looking at a detailed medical history and brain scans how can anyone come up with a conclusion to generically cover everybody.
all addicts have underling mental or chemical imbalances. either chemically induced from mass use, or chemical imbalances in the brain that are environmental, or emotionally induced. one can also be born this way.
before blaming the chemical you take for the addiction, emotions, or action look at the chemical that is already there.
i have dealt with a chemical imbalance for my entire life. when i was a kid till 33YO, the doctors had no clues what was going on, they blamed my emotions and action on everything else. 36 years later they are just now beginning to get a grasp of how the brain works with these imbalances. much of it is still a unknown. i have had problems with jobs, relationship, law, school and drug addiction. after $10000 of rehab, and a few $1000 more in outpatient, they told me i was cured, but destine to relapse for the rest of my life. WHA WHAT? well they lied. the problems keeps coming. only after i had sat down with my family doctor and quit fucking with the specialist did we look at my brain for the imbalance. i have been on med for 3 year for the imbalance i have not even though about my past chemical addiction to cocaine. (which lasted for about 5years)
i now hold a job that has changed my life financially and emotionally. i dont take risks like i used to, the anger is controlled. i dont find myself with all the problem that just seemed to manifest with no reason like in the past. and been puffing the whole time.
edit
as a matter of fact after telling my doctor that the side effects where to much to deal with that i cut my dosage in half, i also told her the with the MJ seem to be doing just as well. her concern was me buying dope off the street that it might have other stuff in it. i told her i dont buy weed off the street (to often). she asked then where do you get it. i told her i would rather not tell her. she reduced my script, and even told me she understands that MJ has medicinal effects with my disorder.
