There is no such thing as a nicotine license, unless it is a local county thing where you live. If so just order online because no one else needs one.
Scott, I owned NicotineRush dot com, (now closed), for a number of years selling Nasal Snuff. Yes, there is most certainly a nicotine license. (and not just one) A retailer/distributor/wholesaler, can't buy any nic product from any tobacco distributor without one.
You can't begin to imagine the hoops anyone selling a nic product has to go through. Federal license. State license. County license, and city licenses.
Age verification was also mandatory.
Many credit card companies wont even take your business.
You have to use a 'high risk' merchant processor who requires much higher processing fees.
Then there is the Federal, State, County, and City tobacco taxes.
If you're an online retailer, you are also required to pay the State, County, and City tobacco taxes of each customers state. (although many online retailers don't)
The paperwork alone was overwhelming.
Then came the PACT Act. This put me out of business.
