I'm happy to see this thread, people don't talk about this much. I have a ritual a few times a week where I , on a somewhat empty stomach but not starving, smoke and then exercise. I put on high energy music and then I either jog, dance, or ride the exercise machine I have, then do push ups and situps and stuff. I find the exercise ecstatic , and my mind doesn't get bored as I do when exercising sober, as many on this thread have noted.
In the course of turning off my mind and doing these repetitive, cardio movements I go into a sort of trance and may have ideas , like, how to solve a problem I've been working on, ideas for a book I'm writing, etc. On a good day I might be inspired to play music, dance, go out in nature, or do a creative project.
Inevitably, though, as I come down, I feel a craving for something, either to munch on some snacky food, or to smoke a cigarette. It's like the "cost" of the benefits I received from the cannabis - exercise trance. Sometimes I can transcend it, or do with an orange or a nice bath. But sometimes I pig out and I slip into a low energy state where I just want to watch a movie, and I feel burnt out and anti-social. I fear that a friend will drop by . If I get a spontaneous invitation to go do something, I usually have to decline. In this way, the ritual affects my life negatively. If I didn't write down or otherwise make an effort to remember the revelations I had while inspired, those may be lost, and I miss out on dream states as well. Still, I've had lots of great revelations which have stuck, and in those states i've also worked through emotional stuff and physical blockages, which is very helpful.
So when I do the exercise machine without smoking first, I notice something interesting. It's less fun and ecstatic, sure, and often I can't go as long. BUT, I am able to reach a sweat, and get endorphins going. I can't get myself to sweat while high, and although I get an ecstatic trance going, I don't feel that release of endorphins. In fact, I don't feel like I've exercised at all! So if I do the exercise first, and then smoke, I feel really good, but I don't get the trance-inspired ideas going.
I try to alternate.
