Quite the contrary man. I used to smoke lots of weed, I just realized how pointless it was. I shouldn't have to come to a life changing decision under the influence of anything. If I can't think critically about my life without a drug that means I need to do something. I also came to the realization that anything that I thought was "life changing" when I was high was something that was influenced by a drug I was taking. As I get older I realize I can still think intensively without the use of a drug.
Sorry for the meltdown
Sounds to me like you just aren't very "tuned in".
To get revelations from weed, you gotta be in a meditative and spiritual mindset. Most people smoke weed and it's just a party thing or a cheap thrill. To get psychedelic effects from weed you gotta do a lot of spiritual work yourself too. The weed won't do it all for you.
Drugs like acid, DMT, and shrooms on the other hand, they do it all for you.
