I personally haven't used any drugs (and started drinking socially only in the past 3 years), but I know some founders (CxO) level using amphetamines almost daily (Adderall from kids' prescriptions or faked shipments from India/Russia) to keep them high performing and focused (US). It also made them more robotic and less compassionate. I haven't seen anyone taking other types of drugs regularly; some smoke cigarettes or weed, but that is becoming acceptable in Europe recently.
