I am sure it is. With all this decriminalization, THC products, and marijuana products in general become very popular. So from my point of view, this will be definitely profitable, because this market is quite demanding right now. Moreover, I recently bought a
THC Vape pen from an online shop, so I can tell you that the market is versatile, and there is room for everyone that want to open a shop. I will recommend you try to accomplish the idea that you have. You never know, maybe your THC shop will become the best. Good luck my friend.
