Hard drugs isn't a category of drugs, but powerful opiates seem to be what's included anyways. I'm not aware of opiate users habitually taking off clothing. Other powerful drugs can make you feel cold, adding clothing. Some people really sweat on acid, which is probably a decent cause of taking off clothing.
