Patients that complained about irradiated weed smoked it more than vaped it. There is a Canadian Bedrocan Review where the patient seems to be coughing more than he usually does and there is also a dutch review of Bedrocan where the patient blames irradiation for the harshness of the smoke and Remo tested irradiate weed with 5-6 patients which they smoked it and did not like very much and I am supposing these a connoisseurs. People have been saying to stay away from irradiated weed, especially that in the US they are switching to cleaner organic meds while here in Canada it feels like they are fooling us.I've tried a few irradiated strains from delta and tweed. ( tweeds not really a good example coz all the strains I got from them had they same underlying smell and was pretty shit) And I can honestly say I didn't notice any difference between zapped and no zapped cannabis as far as taste and harshness (but I do use a vape)
