Can I return/exchange product I bought pre-legalization?

Unfortunately all the cannabis sold prior to Oct. 17th is considered “unlawful” as it was not obtained from a current “government authorized source” and has not been recorded along with a licensee’s licence number. We lived in a grey area whilst being licensed by the city of Victoria prior to Oct. 17th, and are moving forward in a legal, black and white, regulated market. Due to these changes we cannot accept, exchange or even allow previous product on premise.
