Damn good question. I’ve never tried IHT so I don’t know if there’s any other discernible differences. However (and at risk of killing the conversation) snuff is such a personal thing when it comes to what works for you and what doesn’t. Keep what works and ditch what doesn’t. My sinuses are generally wide open, and I tend to need some congestion to snuff Tom Buck or the JHW SPs, otherwise they go straight to the back of my throat, no matter what technique. McC Mild Lemon doesn’t seem to give me as many problems though despite the similar grind. I mixed up several snuffs that didn’t work for me, including many that made me cough badly, and the resultant blend works really well. I stay well clear of scotches and other superfine snuffs. I can’t use mentholated snuffs, as these burn like someone’s thrown acid in my face. It’s not just the interior, but also the outside of the nostils that suffers (burns) from contact. That said, I’m fine with Anarkali and Kailash, and even the occasional pinch of WoS Crumbs of Comfort and Honey Menthol … maybe a different batch of the same snuff would have a different effect. I avoid trying new menthols. Some snuffs (particularly from artisans) give me a horrendous back drip which makes me heave. Similar snuffs from other makers don’t. I still find it frustrating now that I can’t use any of Sir Johnny’s snuffs. They smell fantastic, but my face revolts for one reason or another. I had the same issue with a couple of the Chef’s creations, and so had to stop sampling his offerings. Some of Jaap’s gave me unbearable back drip issues too, and had to be used very sparingly. There are MANY snuffs I can’t use. It’s not that there’s anything wrong with these snuffs, I’m just not compatible with them and had to steer clear. When I first started snuffing I got really frustrated with it, and with myself, and some of that frustration unfortunately spilled out onto the forum. I have simply learned to understand and accept the limits of what snuffs I can enjoy, and stay within them.
