Yeah, I don't get anxious and weed isn't going to harm me through psychological effects but rather physiological ones...
what I feel, and I definitely empathize, is a great, tremendous feeling of spaciousness/spaciness.
And it's very strange, I'm of the most balanced types of characters, yet I have this "self-destructive" tendency. I have no intention of committing suicide, but smoking up makes me feel wholly lost and "leaving". Of course I know I'm "coming back" the next day, but this happy/bad trip is enjoyable...
