'drug'store

Last night I was hanging out at the local Walgreen's after midnight waiting for Amelia's latest antibiotic to be filled. I was more than a little tired browsing the aisles trying to pass the time and I noticed a sign that read " marijuana, methanphetamines, cocaine available behind the counter." I know there are medicinal uses for all these drugs but I thought it was strange that they would state that they had these drugs in the store at all. I took a step closer and realized I couldn't see the top line that said " Drug testing kits for.." Well that makes a bit more sense.
