Your profile says you are 70 is that true? If so my advice of hanging out in bars with young pot smokers might not work! Always a good idea to befriend people in bars that you think has a high percentage of pot users in it. Also, learn the bartenders so they can help you by pointing out the cool people and making you not look like the police.

Vaporizers aren't illegal in most cases until they become dirty and have THC residue on them or they can be clean and in the vicinity of marijuana. Coming in the mail clean isn't illegal.
