Cannabis consumption has become the center of much debate globally. The positive public perception of the medicinal benefits of cannabis and the rise of recreational usage of cannabis necessitate dramatic changes in cannabis reform policy. As a consequence, there is an increase in cannabis legalization around the globe, although it is still facing many rejections. It is crucial to understand the factors affecting public acceptance of cannabis use to support the contextualization and success of cannabis legalization. This review aims to address consumer cultural, social and psychological factors regarding the legal use of cannabis. Based on this review, cultures influence the endorsement or rejection of cannabis use depending on political views, religious sentiments and affiliated subcultures (adult, youth and adolescent subcultures). Regarding the social factors, socioeconomic status, measured by income, education level and occupation, is a key determinant of cannabis use. The beliefs opposing cannabis legalization are due to the negative stigma surrounding cannabis use. Nevertheless, growing awareness about the pharmaceutical and therapeutic effects of cannabis has led to an increase in positive attitudes towards cannabis legalization. Thus, dissemination of cannabis use benefits reaffirmed by scientific evidence could be a strategic way to alleviate the public’s negative feedback on cannabis legalization.

Insects need a sufficient quantity of macro- and micronutrients in their diet for maximising their growth, development, and reproduction. To achieve high efficiency in the mass production of a particular insect species, the quality of the diet given must be considered, both in terms of its chemical (nutrients) and physical (hardness and form) characteristics. Black soldier fly (BSF), Hermetia illucens (L.) (Diptera: Stratiomyidae), is a beneficial insect widely reared due to its easy and cost-effective maintenance. An example of the end-product of BSF larvae (BSFL) is known as BSF oil, which can be used for animal feed, raw material in bar/liquid soap, and biodiesel. To obtain the best quality of oil produced from BSFL, finding an optimal substrate through diet mixing or manipulation is quite necessitated. Fatty acids with more than 18 carbons should be found in the substrate to be absorbed into the fat of BSFL to obtain a high-quality oil. There is a positive correlation between the fatty acid concentration in the substrate and the concentration in BSFL, that the concentration in BSFL is influenced by the concentration in the substrate. This emphasises the importance of the substrate’s fatty acid content in incorporating these fatty acids into BSF oil. Although the oils produced by the insect are especially high in medium-chain fatty acids and monounsaturated fatty acids, yet, to produce on such a large scale requiring further investigations.
