I once spent some time reading through the earliest threads on ECF. There was one where the first people who attempted to make their own
juice were talking. In the first posts they were trying to figure out what the
juice in the cigalikes was made of. After much research they concluded that the nic was mixed with PG. One guy said wouldn't it be great if you could buy nic in a PG solution so it ready to use. Then someone found a source for that. They discussed what percentage of nic was in
juice. Don't even want to think about what they used for flavoring back then.
We have it easy these days.
