If you started in 2011, then you likely had freebase nicotine that maxed out at 20mg/ml before being too harsh for people to vape. It was around 4 or 5 years later that nicotine salts began being used due to how smooth the hit can be, and those can reach +70mg/ml now. There's not really a motive to keep low nicotine disposable vapes in gas stations and the like.

edit: And yeah, this is all anecdotal for me. No clue how much nicotine you actually intake via these methods.

I remember when 20 used to be considered high, and 5mg/ml was probably the most popular (or 3/6 depending who you got it from). Vaping back then largely felt like a fun hobby and was probably at its peak 'healthiness' and 'environmentalness'. Lots of people were happy to give up cigarettes for vaping (or at least try).

Towards the end of that, there started to be hints of legislation restricting the sale of juices, which made things a bit more complicated for consumers.

Then Juuls became popular, featuring higher nicotine content and almost invisible vapor, and nothing was ever the same.

Once nicotine salts were introduced, it hit the fan. It was no longer about the clouds, which freebase and their glycerine introduced. But just more and more nicotine content.
