Are psychoactive drugs with lower lethal doses more neurotoxic (more damaging to the brain)? For example, tetrahydrocannabinol (cannabis) has a much higher lethal dose than benzoylmethylecgonine (cocaine), so could we deduce that cocaine is more damaging to the brain? Moreover, is a mathematical relationship between neurotoxicity and lethal doses known?

Are psychoactive drugs with lower lethal doses more neurotoxic (more damaging to the brain)? For example, tetrahydrocannabinol (one of the active components of cannabis) has a much higher lethal dose than benzoylmethylecgonine (cocaine), so could we deduce that cocaine is more damaging to the brain? Moreover, is a mathematical relationship between neurotoxicity and lethal doses known?

Are substances (drugs) that have lower potential lethal doses more neurotoxic (more damaging to the brain)? For example, Tetrahydrocannabinol (Cannabis) has a much higher lethal dose than benzoylmethylecgonine (Cocaine), so could we deduce that cocaine is more damaging to the brain? Moreover, is a mathematical relationship between neurotoxicity and lethal doses known?
