Heat can be deadly, especially when combined with drug use. Stimulants like meth, cocaine, and ecstasy increase body temperature and the risk of dangerous overheating and dehydration. Overamping on meth is especially dangerous. Depressants or "downers" like fentanyl, heroin, benzos, and alcohol can mask heat stroke symptoms and reduce your awareness, so you may not realize you're overheating.
