It is even less recommendable than in other countries to take drugs or weapons with you, especially as of 2010 since the Mexican government, backed by the US ADA DEA who are actually present in Mexico (!!) have decided to crack down on narco and weapon trafficking. Therefore you likely will be checked at one of the numerous check points, especially in the north as you near the US border. But it's also good to know that the soldiers hardly ever search all the way through a large back-pack, unless you answer their questions really bad. If the vehicle you're riding in does get stopped just stay calm, show your passport, say the magic words "''turista''" ("tourist") and "''de paseo nada más''" ("just passing"), and if they ask to see your stuff open you bag and show them that it's all clothes and stuff.
