Study links early cannabis use and health problems

Researchers find those who began using cannabis regularly before age 15 were more likely to seek care for depression, anxiety, suicidal thoughts and physical health problems as young adults.

McGill researchers find LED interlighting boosts cannabis yields and cannabinoid uniformity

A new study published in Scientia Horticulturae describes indoor cannabis crop outcomes when LED interlighting is used in a commercial setting. Researchers in McGill University’s Biomass Production Lab teamed up with licensed producer ROSE LifeScience and Philips Horticulture LED Solutions to investigate how LEDs impact crop yield, cannabinoid production and electrical energy usage. Findings indicate that LEDs provided increased cannabis crop yield at lower energy cost and achieved higher THC production efficiencies. In addition, LED interlighting increased cannabinoid uniformity.

Smoking both cannabis and tobacco may alter brain’s ‘bliss molecule,’ study finds

People who use both cannabis and tobacco show distinct brain changes compared to those who use cannabis alone, according to a new study led by researchers at the Douglas Research Centre.

 

McGill has become a leader in cannabis science 

On May 5-6, 2025, the McGill Research Centre for Cannabis (MRCC) and Quality Assurance and Quality Control for Cannabis (QAQCC) co-hosted the 4th Cannabis Scientific Symposium: From Plants to People. MRCC has emerged as a world leader in multidisciplinary cannabis science, while QAQCC has trained over 50 graduate students at three participating universities, mostly at the MSc level, in different cannabis research areas including quality assurance and quality control.
