Impact of khat price increases on consumption behavior - price elasticity analysis.
Article in Substance abuse treatment, prevention, and policy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
backgroundThe long border of Saudi Arabia with Yemen is the primary route for khat entry to the Kingdom. As of April 2015, the government of SA tightened the border, making it more difficult to import khat into the country. As a result, local user prices of khat probably increased due in part to higher supply costs and perhaps lower quantities. One anti-drug strategy is to increase consumption cost by increasing the price of supply. We aim in this study to measure the responsiveness of khat demand to price changes.
methodsThis study used a cross-sectional survey design. Two stage sampling was used to recruit 350 khat chewers from four selected primary healthcare centers in Jazan province (South western province of Saudi Arabia). The data were collected during the first quarter of 2017. This study used both contingent valuation and revealed preference methods to assess the impact of price increases on the purchasing of khat. Graphical analysis, paired-samples t-test, and one-way repeated measures analysis of variance (ANOVA) were used to assess the impact of price increases on khat consumption.
resultsThe study results showed a significant decrease in khat consumption amount (t = 8.63, p ≤ 0.05), frequency (t = 30.42, p ≤ 0.05), and expenditure (t = 34.67, p ≤ 0.05) after the tightening of the Saudi-Yemeni border. Hence khat demand is price elastic. The price elasticity of khat demand in Jazan is estimated to be between - 2.38 and - 1.07. Therefore, each 1% increase in price is associated with 1-2% reduction in quantity demanded. This means khat chewers are relatively responsive to price changes (i.e., khat demand is price elastic). Repeated measures analysis of variance showed price increases significantly affect the quantity {F(4, 2.58) = 257, p ≤ 0.05, ηp
conclusionsIncreased prices for khat would significantly decrease demand. Accordingly, we recommend implementing law enforcement strategies focused on disrupting the khat supply chain to realize high prices and so discourage use, hence reducing the incidence of khat-related illnesses.
