The word used to describe the act of a person/s going to the local pharmacy to buy drugs. Like DXM or Dramamine.
"What do you mean we can't get any weed? Well I guess that's because it's illegal and we have to purchase it on the black market. I guess we could go pharming tonight and drugs that are actually dangrous instead of smoking harmless marijuana which we only can't get because it's wrongfully illegal. Oh well, time to go pharming! Let's go guys!"
