When evaluating any investment, consider the possible upside vs. the possible downside. IMO, there's far more upside potential here than downside. Upsides include a dramatic increase in value (outrageous nic tax bills have been introduced in both the House and the Senate) and the risk that the FDA will cut off high-test nic entirely, meaning the only way you'd be able to buy it after that would be to pay black-market prices for product of questionable quality. And even if you don't get married, you could be someone's nico-daddy.Still tossing the idea around of getting more nic. On the one hand I'm like "but what if I meet a smoker and marry her and she wants to vape" and the other is like "but what if you don't and nic doesn't last 40 years." I also really don't feel like decanting more than I already have.
Decisions decisions.

The downside if you never use it or if it doesn't last 40 years? It's limited to a few hundred bucks.
