Having heavily done the whole marijuana-drinking-shrooming thing for a while, and having stopped now, I have some authority on the subject (ppfffff what I mean is I know a little about what I'm talking about.. and I think people who haven't done drugs and have an opinion aren't worth the time to listen). When I was doing drugs my life rapidly became absolutely deeply fear-filled and one anxious rush. After stopping doing all of that stuff, I've learned so much about myself and I am becoming deeply happy. One can draw some severely wrong conclusions from that little snippet. However, the influences on my general morale are not just about the drugs. I think one of the things that happens when you do drugs, is whatever state of mind you are in (i.e. happy, anxious, depressed, philosophical) becomes much, much more intense. 'Aggravated,' if you will. Before I started doing drugs, I was already a generally anxious person with some depression. Anyway... this is longer than I intended it to be. Right now, I'm leraning to understand how I work, so that the fear, the moodswings etc. are all gently observed, and I've found a center that I can come back to. A blissful center. It's partly through the practice of meditation, and partly through Byron Katie work, and much more, that I've discovered how to do this. The thing with drugs is, the experience is very polarized. Most of the time, people who have amazingly, beautifully happy trips, have horribly, terribly sad times when they come down. It's like, if you feel happy, you have to feel sad later. Whereas, when I can learn about myself and work on my happiness level from a sober place, I don't get the swings. Not to say that drugs can't be eye-openers. However, when it comes to happiness, in my experience (and drugs are all about personal experience), drugs are not the key. doo doo doo
Drugs open your eyes, and make you consider what you may have not of considered. Make you see things you may have not of seen, make you hear things you may have not of heard, make you feel things you might have not of felt. Drugs are not the truth however, drugs are just something to help you see with a new perception on the world.
One other thing about drugs is, they are so much about being in the present moment. It's like, if we were actually fully in the moment, we'd be on a trip, just without drugs.
