This paper examines the believability of strong warnings about the negative consequences of drug use among young adults in Australia who have never tried, currently use, or have tried and rejected cannabis. It finds that the strong warnings about cannabis are generally believed by never‐triers. The same warnings are perceived by current users as only slightly believable. Surprisingly, but also consistent with cognitive dissonance, trier‐rejecters of cannabis are the most likely, more so even than never‐triers, to believe the warnings about cannabis. The paper also examines warnings about cocaine and heroin by cannabis usage status. Current users of cannabis, compared with non‐users, perceive the warnings about the harmful effects of cocaine as less believable, suggesting possible “gateway” susceptibility to trial of this drug. But for heroin, all groups perceive the warnings very believable. The beliefs about particular negative consequences that are most likely to lead to discontinuation of use of cannabis, and those that should discourage uptake of cocaine and heroin, are identified.

Despite being the most common illicit drug in the Western world, treatment for cannabis use is not readily available. Primary health care and even specialist drug treatment services have often under‐recognised, and undertreated, cannabis‐related problems. Australian researcher Jan Copeland is one of the few people to test cannabis treatment models. Here she outlines the most effective models for treating cannabis and how they can be applied to other services.

This article is based on a study of 100 young people who were regular marijuana users, which aimed to discover the impact of their drug use on key life transitions. The article identifies the implications for practitioners who work with these young people.

This paper considers the findings of the Beckley Foundation's Global Cannabis Commission Report (Room et al, 2008), an overview of the scientific literature on cannabis, detailing its potential harms and those caused by its prohibition. It moves on to consider the various strategies that different jurisdictions have adopted to deal with cannabis use, before moving beyond the Conventions, arguing that countries should have more autonomy to develop policy best suited to their individual circumstances.Cannabis was incorporated into the global prohibitive regime via the Single Convention on Narcotic Drugs 1961 (United Nations Office of Drugs and Crime, 1961), and is further affected by two later drug Conventions, the Convention on Psychotropic Substances 1972 (United Nations Office on Drugs and Crime, 1972) and the Convention against Illicit Traffic in Narcotic Drugs and Psychoactive Substances 1988 (United Nations Office of Drugs and Crime, 1988). Together, these require that all signatories make production, commerce and possession of cannabis criminal offences under domestic law: in the UK, this expectation is effected via the inclusion of cannabis in Schedule 2 of the Misuse of Drugs Act 1971 (HM Government, 1971). In the half century since the initial Convention was drafted, patterns of cannabis consumption have altered fundamentally; smoking cannabis has transformed from a relatively rare behaviour confined to a scattering of countries and cultures, to almost a rite of passage among young people in many nations. The United Nations Office on Drugs and Crime (2009) estimates that there is a global population of 190 million cannabis users, rendering it by far the most widely used illicit drug, yet, paradoxically, one that is rarely mentioned in international drug control policy discussions.

The purpose of this paper is to present evidence of the therapeutic value of cannabis as a harm reduction intervention with people who smoke crack cocaine.

A desk study of published peer-reviewed material supporting the use of cannabis as therapeutic in mitigating some of the harms associated with crack cocaine smoking.

The use of cannabis as a harm reduction strategy for crack cocaine use has been commented on in the scientific literature since the 1980s. The officially scheduling of cannabis as having no medicinal value hampered further study despite the reporting of positive findings and numerous calls for more research.

There are currently no approved pharmaceutical substitutions for crack cocaine. Cannabis has shown itself effective in mitigating harms for 30–40 per cent of people. Cannabis is inexpensive and readily available and should be allowed for those people who want to use it.

Poly drug use is often framed in a negative context. In this paper, the author shows that with cannabis and crack, the poly drug use is actually a valid harm reduction strategy.

The purpose of this paper is to give a review on the developments leading to the 2017 law on the medical use of cannabis and cannabinoids in Germany, and to present the major advances arising from this law for the supply of patients with cannabis-based drugs and its major limitations.

This paper used an Analysis of the major political statements and documents as well as court decisions of the past 20 years, which can be regarded as the major steps of this development.

Since 1998, when dronabinol/THC was made available in Germany on prescription there have been continuous improvements of the access to cannabis-based medicines. The law of 2017, which made cannabis flowers available to patients on a doctor’s prescription and forced health insurers to pay for a treatment under certain circumstances was a major step. However, many patients, who profit from a treatment with cannabis still do not get access.

The German law on the medical use of cannabis and cannabinoids of 2017 is unique in its kind in the world. Compared to the legal framework in other countries it has several disadvantages, for example with regard to the high prices of cannabis flowers (€20-€25 per gram), and several advantages, for example with regard to the role of health insurers.

In the first study of its kind, researchers from King's College expose the consequences of reclassifying cannabis. Just how much time have the police saved, what does the Bobby on the beat think about the change, and what would be the consequences if it were put back to Class B?

The present work highlights the outstanding properties of Cannabis sativa that can be harnessed for various utilitarian functions and its climate friendly properties.

In this paper, the authors reviewed current research on all possible utilities from household work to manufacturing of various products that are environmentally sustainable. The authors have presented some of their research on this materials and also exploration of hemp as an archaeological material based on the findings from wall paintings of Ellora caves.

There are references of hemp use in mixing with earthen/lime plaster of western Indian monuments. Around 1,500 years of Ellora’s earthen plaster, despite harsh climatic conditions, survived due to the presence of hemp in the plaster that adds durability, fibrosity and its capacity to ward off insects and control humidity. Furthermore, the outstanding quality of Cannabis as carbon sequestrant was harnessed by Indians of ancient times in Ellora mural paintings.

This work discusses some relevant literature on the potential use of hempcrete aligned with Agenda 2030 of sustainable development goals.

There are several research going on in producing sustainable materials using hemp that have the least environmental impact and can provide eco-friendly solutions.

The authors impress upon the readers about multifarious utility of the hemp and advices for exploration of this material to address many environmental issues.

This paper presents both review of the existing papers and some components coming directly from their laboratory investigations.
