How long is a persons ability to drive impaired after using Salvia?
A. Most people feel they can drive safely by 3 hours after smoking Salvia, or 4 hours after chewing it. Many believe they can safely drive even sooner than this. The duration of impairment after drinking the infusion might be up to 8 hours. But studies of the duration of impairment, after taking Salvia by any route, have never been done. Q.
