Introduction: Our research group is conducting three large randomized placebo-controlled trials of medicinal cannabis for cancer symptoms. All participants are invited to take part in a posttrial surveillance study. Methods: Participants were given the manufacturers dosing instructions and liberty to titrate to effect. ⋯ Conclusion: Participants felt confident making changes to their medicinal cannabis dose within the limits suggested by the manufacturer of each product. A number of benefits and adverse effects were ascribed to the product. Benefits were similar to those described in previous studies.
