As I wrote, I don't think there is any danger in shrooms from the possible slight BP increase. I haven't been able to find any measurements on BP increases from shrooms, but I presume there are some, since one should think it has been measured as a standard procedure on the few scientific experiments that have been carried out.
ok......... so anyone that has had a heart attack and has HBP should not be eating boomers?
It's another story for mescaline, and possibly also for high doses of LSA. I would not go near them if I had very high BP.
