Funnily enough, a law in Germany just went into effect today that makes it far cheaper (assuming you vape less with more nicotine, certainly holds true for me, I’m on 0mg nowadays) to vape with a lot of nicotine. The law is essentially a tax per ml. But doesn’t care what ml, pure propylene glycol, vegetable glycerine, flavor concentrates, nicotine, whatever, as long as the intended use is for vaping.

I'm not sure where you're getting those numbers from. The vape shop near me sells nicotine salts in 25mg/ml to 50mg/ml ranges, which roughly translates to 2.5% and 5% strength. I've never seen something so low as 5mg/ml.

maybe you're only using a disposable brand like Juul? You could go down to 3mg here in Canada with the one I used.

Picking a salt liquid at random, this one lets you go down to 1mg, since they probably add the nicotine to a 0mg product:

Interesting, I'm used to the US market. Back when I was a regular user (as opposed to sometimes-caving-and-buying-a-dispo quitter), salts were usually 25 and 50, with lower strengths provided by freebase nicotine juices. I think the last freebase juice I bought was a 3 or 6mg, but those were less common.

Disposables are usually 5% salts over here, afaik.
