A Canadian cannabis tech company has pulled out of the CES gadget show after being given constraints on how it could promote its products.

 

Nearly a dozen states allow the use and sale of marijuana for recreational purposes, and policies around the world vary.

 

CES organizers say marijuana's acceptance isn't widespread yet. They prohibited Keep Labs from mentioning the word cannabis, showing cannabis in promotional materials or discussing what the Keep device does.

 

Keep co-founder Philip Wilkins described the move as "naive." But Gartner analyst Werner Goertz says organizers are being smart in being cautious.

 

The annual technology show in Las Vegas opened Tuesday.
