Salvia’s effects usually appear in less than 1 minute and last less than 30 minutes. Short-term effects can include:
- intense hallucinations (seeing or feeling things that aren’t really there)
- mixed senses (such as "seeing" sounds or "hearing" colors)
- feelings of detachment (disconnected from one’s environment)
- mood swings
There also are reports of people losing contact with reality—being unable to tell the difference between what’s real and what’s not. Many of these effects raise concern about the dangers of driving under the influence of salvia.
The long-term effects of salvia have not been fully studied.
