Easy to access, but beware there are police watching, better have lots of bribe money or get butt fucked in a Mexican Jail
I don't want to take away from the joy you got out of writing that butt... but you can't go to jail for simple possession in Mexico anymore. Perhaps some cops may try and get a bribe from ignorant or fearful people but the law is in process of changing to full legalization and it's already been decriminalized.

I would not recommend bringing THC in any form across the borders. Trafficking (crossing a border with an illegal substance) is a pretty serious offence. People do it and get away with it but is it really worth the risk?
