This is true, however if you do this more than every once in a while you will jack up your tolerance for a long time. If you make a habit of tripping frequently, even weekly, for long periods of time, it makes it very difficult to have profound/meaningful trips... they become rather ordinary feeling, still fun, but basically a waste and you're unable to have trips like you used to unless you take a lot of time off. Tripping once a week for a few weeks and then taking a break works pretty well, but you have to be careful. it's best to wait at least 2 weeks between trips, and even better to just trip infrequently when the time is right. I tripped so much years ago that it took me a good 5 years with no psychedelics to be able to trip worth anything again.
