No Written Cannabis references
There are certain words that the Major Phone Carriers monitor messages for. When these words are found, they are flagged, filtered and then eventually blocked and blacklisted. Always stay away from using specific Cannabis words, an example of some of these are: Cannabis, Distillate, Joint, Reefer, Marijuana, 420, Indica, Sativa etc. Basically any word that references anything to do with Cannabis that doesnt have any other use. Words that have multiple meanings operate in a grey area (ie: joint, blunt) so refrain from those words if possible. Grey area words like that do not get flagged and filtered by a system, but they could be flagged to be looked at by a human, whom after seeing the context that you're using them in, could blacklist your number.
