A lot of people mentioned losing the ability to socialize when they were high, but what about socializing with other stoned people? Sharing a high is a great way to connect, if that's what you want.
What really matters when you smoke, or actually before you smoke, is your intention for smoking. What do you want to get out of the it?
I've had a lot of great realizations simply because I intended to before getting high. Maybe I would have had them anyway, but getting high makes it really easy (for me at least) to get into a flow state where ideas and realizations come quickly and easily. For example, I figured out my life purpose approximately 10 minutes after getting high, because that's what I intended to do.
But, as with most things, it is best in moderation. Many times I've gotten high and felt mentally cloudy, but that's usually because I set no intention beforehand.
I also want to add that while logical thinking may not work for you while high, that can be overcome with practice. I'm a programmer (which requires very clear, logical reasoning), and for a while I couldn't program high, but I practiced alot
, and I think that made me a better programmer.
