A quick search found this article, in which it states that while the church is against recreational use of cannabis, the are in favor of reaping the beneficial uses of medical marijuana... But I didn't read the whole thing.
Here's the sub-head:
September 18, 2018
"Mormon church leaders are calling for
Utah lawmakers to pass medical-marijuana
legislation by the end of the year even
as they urge people to vote against a
ballot measure that would legalize medical
marijuana in the state."
Robert Kirby, noted future ex-mormon, noted, "I’m a marijuana user and a Mormon"
There's a good bit of money to be made here so even if the church never comes out with specific rules, it's pretty much a given that they'll allow crafty members to find a way to profit (and tithe) on marijuana and cannabis.
