It's becoming big business here and other states are looking to Colorado on how we manage laws, taxation, etc.
We've had issues with edibles for a while with people consuming more than they should because the potency of each piece wasn't clear.
I'm no expert on the subject but new packaging, labeling and potency restrictions that went into effect in 2015 helped. Packaging has more warnings and should be less attractive to children. There's been a number of cases where children mistakenly ate the edibles thinking they were candy or other treats and ended up in the hospital. Same with pets.
No such issues with vape pens and similar devices.
