I have joined these boards as part of my attempt to help a family member who is looking to get their MMAR or MMPR ticket. I do bring a lot of experience in legal pharmaceutical production under GMPs: the regulations that ensure safe product for human use. I have experience making injectable products for clinical trials - safely. Yes, that likely sets me apart from this community. Irradiation is likely being done for the same reason Bedrocan and parts of the food industry do it; less risk to the patient which turns into less risk for the company. Another possibility is that Health Canada made them do it and now they would rather stick with it rather than risk switching away from a validated procedure. I can't find any credible published data that shows irradiation has any negative impact on the efficacy of their product or Bedrocan's. As to the milling, I see that being interpreted here as powdering with no evidence that is actually the case. Ditto the charge of adding in plant parts other than the flowering tops.
