When I first got into e-cigs, the first juice I ordered was a Marlboro clone from
DIY Flavor Shack, it's 48mg nicotine, which is very very strong. 2 puffs of that and I got light-headed, just like smoking a real marlboro. But, it doesn't really taste like an analog, and the throat hit, while strong, wasn't exactly the same.
Another juice i ordered was a dark beer flavor from
Totally Wicked, called Extra Stout - 36mg nicotine. They use (from what I read) very clean, pharmaceutical-grade nicotine and PG liquid. The throat hit can be PAINFUL! In a good way. It's the strongest throat hit I've experienced yet of any e-juice, and it's not limited to their Extra Stout flavor. I have a couple others, and they all offer that much needed throat sore!
Then finally - and this is the good stuff - I got some tobacco flavors from
Alien Visions E-Juice. This stuff really, really tastes tobacco, it's a very unique flavor that no other vendor has - I suspect it's all custom-made. At 24mg strength, the throat hit is comfortable, and the taste... really, really satisfies!
In the end, between these 3 vendors' juices, I can honestly say that the Marlboro reds I used to smoke are weak-tasting and the throat hit doesn't compare. I tried a Marlboro one night and it didn't do anything for me, so I picked up my e-cig and never looked back
Hang in there, and best wishes!
