I have not smoked pot but I used to be a heavy drinker when I was in the Navy. Luckily, it never really damaged my life (DUI, lost job, etc) but I realize now it was a waste. I was trying to ‘drop out’ and escape from the stresses of submarine life. When I sobered up the problems just came back. Substances don’t solve problems or really help anything. There are a lot healthier ways to address problems. I highly suggest the writings of Marcus Aurelius. They are easy to read and short. It has really taught me to focus. Your friend should try this or maybe some therapy or a healthy hobby. Coping strategies can be learned. In addition to this, I think your friend needs to realize that smoking pot can really close doors. You can’t even work at Wal Mart without a urinalysis. Many careers ask that you never have tried drugs. I know this is unrealistic but true. Also, drug convictions can keep you from getting federal financial aid for college. Food for thought. Finally, I should add that I’m not now a tee-totaller. I learned to drink in moderation which is actually more enjoyable.
