"I just picked up Sativa and Indica at my local dispensary but they were unsure of the Valium question. "
You should consult with an MD about this. Amongst things to consider: if you have already taken a Valium and it’s in your system, it will be difficult for you to accurately evaluate/experience the effects of the edible and learn how it is benefiting you…
Many patients I have spoken with use cannabis ‘alone’ so that they can avoid taking Valium or other conventional medicines.
