"tripping twice in a week is playing some Russian roulette with your brain." That is some ignorant shit right there!
I don't think so.
I'm not a doctor or a scientist but I think you're incorrect and trying to rationalize taking some fairly big chances.
And yes, to another poster, I do think LSD is different and more chancy than shrooms.
But hey, adults can make adult choices, and I think most people involved understand that there's an element of risk each time they trip, in whatever form.
You will have to explain these big chances to me. Why would taking the same thing a day or two later be more of a risk than the first time? Sorry that hasn't been my experience. The first time with L or with a particular batch of L is the most risky. We used to buy vials in the late 80s- early 90s and take progressively doubled doses for weeks straight.
