In the case of how hot a jalapeños is going to be, is a factor of growing conditions and watering schedule, which probably plays a critical role in the production of alkaloids in the different species of cactus.It does not matter really. ll in how you prepare the tea.

You could get a San Pedro that was twice as much mescaline as a torch or the other way around. It's like asking what the hottest pepper is. I've had jalapeño that would melt your face...
