Wow! Wonder what this guy wants with all those pure salvinorin A crystals - several hundred mg's is a pretty large amount, especially when seen in conjunction with the special type of trip it delivers...
But I think he had to do lots of trials before arriving at such a convenient procedure - and that this is optimized for salvia leaves and nothing else.
With cacti for example, it might be a completely different procedure that leads to such a very presentable sucess...
(still very impressive!)
