Unfortunately still seems sketchy all around at the moment. I haven't even looked at CBD hemp strains as I'm not going to pay the same price as street weed for a gram of something that's worse quality than thai stick(or dressed up to be something else). I go to highkind (formerly synergy) for my extracts mainly. I use CBD distillate or isolate in a dab rig, I sort of know what's what with that - they do still seem a bit added terpy at times.
For herbs to vape in your beloved herbal vaporiser I have had enjoyable results with a 'chillzone' brand hemp tea. One of them was lemon verbena with hemp tea and a few other herbs. Not high CBD content but it was about a tenner for an ounce ish pouch full. I guess it all depends what you're looking for. I did get the odd nice strain a few years ago but I got disheartened and found cheaper, more pleasurable alternatives as mentioned above.
Hemp tea on its own is sort of enjoyable and placebo like for me - great to have on a lunch time at work instead of the 'full fat' variety. I know I've had a vape but I still have a clear head. The lemon verbena does add a bit of a buzzy effect for me too.
Just offering an alternative, I know it might not be exactly what you're looking for but there's quite a few brands of hemp tea that have been around for many years, these aren't spraying with anything or trying to dress it up by adding terps. Just treat it like shake
Still a shame as it was nice to see a bit of a 'legal weed' industry over here and it was nice to think I was supporting this but it has been stomped on - I guess rules and covid and people taking advantage of the situation/consumers combined didn't(doesn't) help. Some fire looking CBD hemp strains in the USA and Europe.
