15 years as a Copenhagen user and zyns fucked me up lol

Been dipping Copenhagen wintergreen for the better part of 15 years and I decided to see what all the hype was about around nicotine pouches. Got the 3mg spearmint zyn and within 5 minutes I had a nice buzz followed by that overall sick feeling of too much nicotine. I started to do some research and looking into the nicotine content of a pouch of Copenhagen wintergreen and found some lab tests from different places claiming anywhere from 14-21mg per pouch. So why such a shitty reaction to it? Maybe synthetic nicotine just hits harder?

Anyway since then I ordered some of the alp pouches. Flavors are ok. All the mints just taste like the mint dental floss lol. Problem is I don’t feel like I’m getting much nicotine and find myself reaching for the Copenhagen more often than not. Today I got some rogues and I love the flavor and the feeling seemed more similar to traditional tobacco but was still a little overwhelming after 15 minutes or so. Are there any brands that just used extracted nicotine from the tobacco plant rather than synthetic salt? I like the long smooth release rather than that quick all at once feeling.
