The aim of this study was to determine the frequency of sister-chromatid exchanges (SCEs) in heroin-cannabis, heroin and cannabis addicts. The group of 84 subjects consisted of 42 controls, 16 heroin-cannabis addicts, 12 heroin addicts and 14 cannabis addicts. The mean number of SCEs/cell was 12.95 in heroin-cannabis addicts, 12.05 in heroin addicts and 11.99 in cannabis addicts. These values are significantly (P less than 0.002) higher than the mean values found in controls. This increase in SCEs may be related to reduced DNA repair in chronic drug addicts, which would allow the fixation or retention of a greater fraction of the DNA lesions caused by normal environmental exposure.

Importance: Cannabis use has increased globally, but its effects on brain function are not fully known, highlighting the need to better determine recent and long-term brain activation outcomes of cannabis use.
Objective: To examine the association of lifetime history of heavy cannabis use and recent cannabis use with brain activation across a range of brain functions in a large sample of young adults in the US.
Design, Setting, And Participants: This cross-sectional study used data (2017 release) from the Human Connectome Project (collected between August 2012 and 2015).

Background: Studies across multiple addictions have suggested that repetitive transcranial magnetic stimulation (rTMS) applied to the left dorsolateral prefrontal cortex (L-DLPFC) reduces cue-induced-craving (CIC), however there are no studies in treatment seeking participants with cannabis use disorder (CUD). In this secondary analysis of a previously completed trial, we explore whether a multi-session course of rTMS reduces CIC in CUD.
Methods: Seventy-one participants with ≥moderate CUD (age=30.

Cannabidiol (CBD) is one of the major phytochemical constituents of cannabis, , widely recognized for its therapeutic potential. While cannabis has been utilized for medicinal purposes since ancient times, its psychoactive and addictive properties led to its prohibition in 1937, with only the medical use being reauthorized in 1998. Unlike tetrahydrocannabinol (THC), CBD lacks psychoactive and addictive properties, yet the name that suggests its association with cannabis has significantly contributed to its public visibility.
