It's mostly unrelated.
"The elasticities for alcohol and tobacco expenditure are negative and insignificant"
"No evidence was found of an increase in spending on alcohol, either in the
general villages or the tribal pilot. If anything, when asked whether they were buying
more or less of specific food items, a slightly higher proportion of households in basic
income villages in both sets of pilots said they were buying less alcohol than before."
Another way to look at what people when they have enough money to not need to work, is to look at people who have enough money and don't need to work.
Bill Gates, spends his time eradicating diseases in Africa.
Elon Musk, started a few new companies and works as an engineer.
Warren Buffet, continues his job as an investor.
Arnold Palmer (golf legend), spend his older days designing golf courses and running golf shops.
Donald Trump, runs a country (where he is running it is outside the scope of this discussion).
Charlie Sheen... druggies will be druggies, no matter how much money they have (or don't have).
You just don't see any evidence of people with money suddenly turning to drugs en-mass, or suddenly turning away from drugs*. They mostly continue to do whatever they where doing before hand. Though people will work for themselves rather than someone else, if given the opportunity.
*The slight decrease is use is mostly due to reduced stress and increased security. It helps those people who turned to drugs because they feel insecure or hopeless, and now with money, they don't. (Evidence in the first link). You could, for instance, afford to leave an abusive relationship instead of turning to drugs to kill the pain. Not a common thing, but it happens.
