Not at all. I quit smoking cigarettes around 5 years ago, I used cannabis as a crutch. I was able to quit smoking cigarettes "cold turkey" because of that crutch. Now, realizing I traded one addiction for another, I am considering quitting cannabis. I have recently drastically reduced my consumption, successfully.
When I quit smoking cigarettes I also stopped drinking, somehow they went hand in hand.
Do I have a bit of an addictive personality? Yes. I've had bouts of addiction with other drugs when I was much younger. Now, I'm 31. I refuse to use anything but cannabis related products. I don't even use prescription drugs and I haven't seen a doctor in years.
I'm looking forward to legalization next year, here in Canada, we're going legal nationwide in the spring of 2017. Actually, our government announced it on 4/20/2016 if you can believe it. lol
When I was younger I definitely drank to get drunk, but since about the time I quit smoking I really haven't been able to do that. I can enjoy a couple of drinks, but I quickly end up not wanting it. Quitting cigarettes changed the taste of everything, I gained a lot of weight just because of how different everything tasted. I smoked cigarettes from the ages of 11-25. So, I really had no memory of what food tasted like.
I do find that my memory has probably been negatively affected, especially in recent years. I do lose my words in the middle of a sentence and sometimes completely forget what I was talking about while I am talking about it. lol. Maybe this is from the thousands of exstacy pills I took as a teenager, though.
The experts say wait until you're 25, and to only use it occasionally. I can't possibly know if I would be any different had I done that, but I can say that I would probably agree with them as far as when it comes to my own children. I would like my kids to wait until they are at the recommended age.
That being said, many studies are inconclusive or biased. Worse yet, we're not getting enough study because of the treaties and schedule 1 rating. Hopefully, with legalization gaining steam federally in the USA and already expected next year for Canada, we can expect to see more research being done.
