I'm sure it's not just the little town I'm from that's exploding with the new THC cartridges. The one on the left is from Amber industries. Very potent. The one on the right I've only had 1 so I can't give an accurate rating. I've seen some other brands I wasn't really pleased with this brand. I would not pick this one first. I've recently started making cannabutter. I fell in love with it after the first time. It helped my back pain and with my anxiety being debilitating at times this is a fix for it. I love the mental stability it gives. I've never felt better than when I'm medicating with butter ! I remember sitting there when I was a teen-ager and dreaming of this day. If it will just migrate East at a little faster pace I'll be just perfect!
