Marijuana is a gateway drug that’s associated with violent crime. But kids in Washington aren’t using the drug at higher rates since it was legalized and it has no conclusive link to mental illness.Those were two of the claims made respectively by local law enforcement and the county’s public health officer at a Clark County Council work session Wednesday morning. Although Washington voters legalized cannabis in 2012, Clark County passed a ban on recreational cannabis businesses in the unincorporated areas two years later.The county council previously reconsidered the ban, but backed off last year. After the council’s composition changed following November’s elections, the council is again moving toward lifting the ban.Councilors Temple Lentz, Julie Olson and John Blom have expressed varying degrees of openness to lifting the ban while council Chair Eileen Quiring has opposed it. Councilor Gary Medvigy, who was appointed to the council in January, said after the meeting that he’s undecided.As the council has weighed the question, it’s considered how lifting the ban would affect youth, law enforcement and social services. All these topics were considered during the work session. At the end, no councilor seemed to have changed positions as the county moves forward, which will likely involve another work session on planning and zoning, followed by a public hearing.
