How long after a minor concussion can i smoke thc or take edibles?

Is there such a thing as a “minor concussion”?

Not clear from your post, as to the reason you wish to ingest cannabinoids subsequent to your head injury. Nor do you provide timing details or severity extent. Best to ask this question via a virtual consult on HT (www.connect@healthtap.com)

Ask your doctor who diagnosed your mild concussion. You may get a more serious concussion if you smoke more weed and eat edibles and lose control of your self and environment.
