Maybe things have changed but in 2016 I was unable to get life insurance in CA due to admitting to recreational cannabis use with a vaporizer. A ridiculously expensive “smokers” policy was the only thing on offer.
There was a whole section of my application regarding cannabis usage. I provided my medical rec. There was a question about seeing a psychiatrist regarding cannabis usage (no). No questions about consumption method. My premium was that of the quoted non-tobacco premium, so I don't think it was affected at all.
