Never detox “cold turkey” without help because not only is it very dangerous, but it is also usually ineffective!Furthermore, because the likelihood of relapse increases as you don’t seek help, so does the chance of an overdose. After detoxing, it’s not uncommon for someone’s tolerance to decrease over time. Yet when relapsing, usually the addict will return to their previous high dose. This makes an overdose very likely. Medical support can also decrease the chances of relapse.
