i can control the effects, but it may be a placebo. is that what you're talking about, controlling the effects? i mean, if you try to feel high right now, even if your not, you can pretend you're high. its just a matter of paying attention to your senses and trying to percieve them differently. i find that when i get really deep in thought i dont even realize that im high, i forget all about the physical. doing the opposite (not thinking, being aware of your vision and senses) might lead to you feeling higher
