I have lots of experience passing glass with ENTP and INTP friends. It does open up their sensory perception - primarily the taste buds!
The INTP thinks he plays guitar better high. It does sound way more fluid and pleasing to my ears. I think it relaxes him, opens up his ears, and gives him easier access to his emotions which are then reflected in his music and voice.
While high I can really get into Ne discussions with them which is a fun area to explore. Otherwise I will just listen but usually not participate.
MJ is weird with me. Sometimes it really gives me access to my Fe and I want to connect with my friends, other times it allows me to detach completely and basically become emotionally unavailable.
For the most part I enjoy it when alone or with one close friend. It's definitely NOT a social drug for me. My deepest introspection comes while high, alone, and completely detached from reality. Since it gets my Ne going, and I pay attention to people's behavior and words, I get paranoid about what people really mean. Maybe that's why I detach.
I love the increased sensory perception it provides. Swimming, running, cycling, anything that requires action and intense focus on physical movement is exhilarating. I seem to be able to get into my groove easier.
Recently I've experimented with LSD, psilocybin, salvia, MDMA. Those, as well as cannabis, are psychedelics that alter our perceptions and that's what I enjoy about them most - how they act like a key to locked doors in my mind and allow me to perceive things in ways I probably wouldn't have considered while sober. I strongly believe that MDMA, LSD, mushrooms have a medicinal use in psychology.
Cocaine turned me into a person I do not want to be. Alcohol will do the same. Very easy to binge on cocaine and alcohol. Opiates are downright dangerous and intensely physically addictive for me. Benzos are boring.
Ironic that my gateway drug was a prescription for Vicodin when I had my wisdom teeth removed. That was the point I knew opiates were dangerous for me.
