1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundLittle is known about young adult medical marijuana patients (MMP) and their marijuana using patterns and practices, which includes frequency of use, sourcing of marijuana products, forms/modes of administration, and patterns of illicit/prescription drug misuse, compared to non-patient marijuana users (NPU).

methodsYoung adults (N=366) aged 18-26 years old were sampled in Los Angeles in 2014-15 and segmented into NPU (n=156), marijuana users who never had a medical marijuana (MM) recommendation, and MMP (n=210), marijuana users with a current, verified MM recommendation. Differences regarding self-reported marijuana and other drug use during the past 90days are expressed as unadjusted risk ratios or differences in means.

resultsMMP reported significantly greater mean days of use (76.4 vs. 59.2, p<0.001) and mean dollars spent on marijuana products (564.5 vs. 266.9, p<0.001) than NPU. Approximately one-quarter (22.6%) of both MMP and NPU report selling marijuana obtained from a dispensary to someone else in the past 90days. MMP were more likely to report vaporization modalities for concentrates (URR=1.5, 95% C.I.=1.2, 2.0) and for marijuana (URR=1.5, 95% C.I.=1.1, 2.1) than NPU. Though not significant, trends toward lower misuse of prescription drugs in the past 90days were observed among MMP compared to NPU.

conclusionMMP reported greater access to marijuana via dispensaries, more frequent and intensive use of marijuana, and greater use of non-combustible forms of marijuana compared to NPU. MMP reported less recent misuse of prescription drugs compared to NPU.
