As mentioned above, not seeking treatment right away can have severe consequences, including long-term damage, coma, or death. How well the individual dose afterward depends on how much meth they took, how long they’ve been using it, and how fast they received treatment after the overdose. The fastest they get help, the better their odds are of a full recovery. As the article we shared above mentions, crystal meth is not the same today as it once was, meaning that symptoms like psychosis and paranoia can last up to a year after you stop taking crystal meth. Even if you treat it aggressively, it can persist for quite some time. Falling asleep and problems with memory can also plague you permanently. Skin changes and tooth loss are also permanent unless you receive cosmetic surgery to deal with the issue. Further disability can occur if you experience a heart attack or stroke, which can occur as a result of very high blood pressure or body temperature. The long-term prognosis depends on the organs affected. Your safest bet is to stop using crystal meth and seek help before something happens you can’t change.
