The withdrawal symptoms and the timeline that you experience these effects will depend on varying factors. Some of these include the dose you used, the length of time you used bath salts, and your last dose will affect the withdrawal experience. There are genetic factors that may affect how drugs impact you. If you have a predisposition or history of suicidal thoughts, mental health issues, or depression, withdrawal symptoms are likely to be more intense.Some people explain that bath salts follow a withdrawal timeline in two distinct phases: a crash, which is characterized by depression and lethargy, and withdrawal that is characterized by intense cravings. Some studies, however, don’t support the model that suggests these symptoms will fade gradually.Stimulant withdrawal can appear as soon as 90 minutes after your last use. MDPV has a short half-life similar to cocaine. Amphetamines that are sometimes mixed into bath salts have a much longer half-life, which will affect your timeline. The symptoms may come on quickly but can take more than a week to disappear. From start to finish, the symptoms can last between seven to 10 days.
