Yea i personally cannot tolerate salvia. Somewhere between the chills and the intense fear i get uncomfortable..
Some people love it though and I totally respect their ability to withstand salvia. Its a true test of character
Under no circumstances should this or any other plant/drug be made illegal, however! The potential for spiritual growth is amazing with these substances!!

How about the potential economic and entertainment aspect of this plant?

I can imagine specialized Salvia "Tripping Stations". Small buildings, warmly lit with liscensed shamans as "bartenders" and elaborately dressed hosts and hostesses.. with darkened booths set for timed individual or group trips complete with music and aromatherapies (offering a vast selection of music and scents). Each room could have different themes, for instance a Cyber Room loaded with blinky futuristic lights,strobe lights and overhead screens with weird videos..mm..ive got even better ideas for LSD Theaters
