OOOOOOO mescaline. crazy shit. ha ha ha. Dude I can't count how many times I've dropped acid, lot's of it and amazing shit. Mushrooms countless times, and mescaline at least six or seven. As well as ketamine and various other party favors that I find to be much less harmful than most drugs. I definantly know where your coming from on the change of weed high. I believe that the reason for this is because you've essentially expanded your mind. For a solid month after dropping acid I feel much different and a bit more fucked up from weed. Going on trips tends to change your thinking patterns a bit, open up parts of your brain you don't usually use, and feel intense and different sensation's that your not used too. The residual thoughts from a trip, at least what I can remember, can have an affect on the way you think or feel about certain things for a good time afterwords.
The effects you feel when you smoke should go away within a month or two of not tripping. As far as revisting the state of mind you were in tripping can be either a good or bad thing. I feel like I look at things in a lot different because of my trips, but I quite enjoy my way of thinking now.
The kind of weed you've been smoking may also affect your thoughts. I find that a good indica will give me good stoney high after tripping, but with a lot more visual affects. A sativa on the other hand may spark some deep thinking in my head and get my gears turning...which may result in a little paranoia.
But hell, the way I see it unless folks aren't in a very solid state of mind, are loaded with irrational fears, or are very emotional probably shouldn't trip. But if you can handle a trip well and enjoy it, I believe it can be healthy for someone to occasionally expand their mind a bit.
You'll be just fine though, if you really don't wanna feel like that, just don't trip!(not recommended)
