Consumption tax will result in a black market.
Actually, both will exist, regardless. The black market is very much alive and well already.
Here is the difference: While both would continue to be against the law, the black market adds an additional element of risk (quality of the product itself).
For example, one of the biggest black market consumables is prescription medication. Namely, Viagra. However, in confiscated shipments they've found extremely dangerous chemicals (in one case, even rat poison). Potential buyers are 100% unwitting to this prior to consumption.
The black market exists now because of the price of products (sales tax doesn't help, but is low enough that it's not usually the dealbreaker). While a consumption tax may affect it, you'll have to remember that there will be additional spendable income, and many will take on the additional cost in order to ensure safety and peace of mind.
I am acquainted with a few people who deal on the black market as a full-time enterprise, and they aren't nearly as excited about the idea of a consumption tax as you'd think, because they see it as basically a trade-off. More spendable income will offset much of the higher tax on products, so they don't anticipate it ushering in the economic Christmas that some suggest.
