I just visited Mexico, Tijuana. It was a nice tour arranged by some people at the hostel I was staying. There were 21 of us. The first thing I noticed where the number of pharmacies where you could buy your medicines. There were multiple pharmacies in every street. Apparently in Mexico you can get a lot of drugs without recipe and a lot of Americans make use of this.
The rest of Tijuana was one big tourist trap. I didn’t like it so much.
