Tolerance can in fact cause an overdose, because the greater tolerance you can get the more of a certain substance your body will need eventually leading your body to take more than it can handle leading to overdose and death.
Alcoholics Anonymous provides a support system for those dealing with alcoholism because it allows people who have the same issue who can relate to each other motivate each other to stay sober. Hope this helps! :)
