Pennsylvania lawmakers have unveiled several bills relating to cannabis use. Officials say the four bills focus on de-regulation, education requirements and protections for medical cannabis users and stakeholders. Lawmakers say one of the proposals would allow clinical registrants to continue hands-on work with cannabis plants to aid research universities and state physicians. Another separate measure relays 10 lawmakers’ agreement that the federal government needs to remove cannabis from Schedule One classification. Such a bill would de-schedule cannabis for recreational use.
