Side Effect is a very nice sweet/boozy/tobacco fragrance. It's quite smooth and creamy and a masculine fragrance. So, while I like the scent itself, the overall package has a number of negatives for me. It would certainly work well for a guy who likes sweeter fragrances. It ended up being too sweet for me. My preference for a boozy tobacco is Kutay which has a touch of sweetness but isn't as sweet as Side Effect. I also was thinking about it from the perspective of a smooth and creamy masculine scent. Maybe add some incense and resin. What I was creating in my mind and confirmed with testing is none other than Boss Bottled Absolut (2024 version) which fits the smooth and creamy groove better for me than Side Effect. Lastly, while Side Effect is a nice scent, it also struck me as very designer-ish. It just can't justify the purchase price.
Longevity was very good with very good sillage for a few hours.
