You can spot a meth head from 200 yards away simply by their specific gait. Why do they all have the same strange walk? Does the meth affect a specific part of the brain that causes that gait?
Meth increases dopamine availability...
probably alters inhibition/disinhibition in the basal ganglia?
You can always tell just by the face. Meth rots out the jaw and teeth. They all have the same “skeleton” look to them.
Yep, tweaker jaw. 400 faces a minute.
