There are many Gateways...but I am talking of the more oral kind...a gateway which might be the original gateway of all gateways...
A double whopper with cheese..
I'm thinking of SUGAR, the root of all evil.
Good point! Sugar gets a lot of people.
Caffeine in chocolate is the first recreational drug most people are exposed to, so if you buy into the gateway drug theory, chocolate is the true gateway drug.
Alcohol and prescription drugs.
Greed, to have the disire to want more than you need?
Oh I am going with chocolate with alcohol and drugs being a close second
