Strength of recommendations was not assessed.The Canadian Coalition for Seniors’ Mental Health recommends that patients with cannabis use disorder should be considered for residential treatment if they are unable to effectively reduce or cease their cannabis use (level of evidence: Low; strength of recommendation: Strong).
