It's my right to ingest tobacco, marijuana and alcohol.
No, it's not. The government could outlaw tobacco and alcohol. The federal government and most states did outlaw marijuana, with few exceptions - and the fed prohibition is still in place.
You don't have a Constitutionally-protected right to ingest those things. But the SCOTUS has held that you have a Constitutionally-protected right to bear firearms. So it's highly likely that SCOTUS would treat a specific tax on firearm usage under the same rubric as Grosjean, and find it prohibited as an unconstitutional infringement on a constitution right.
