Featured News: Need for Multiple Naloxone Doses on the Rise
The percentage of people treated for a drug overdose who need more than one dose of the opioid overdose antidote naloxone is on the rise, a new study suggests.
The environmental factors that contribute to marijuana use and alcohol dependence differ significantly, but similar genes are involved in influencing people to drink and use marijuana, according to researchers.
WebMD reported Dec. 18 that a study of identical and fraternal twins ages 24-36 concluded that more than half of the variance in alcohol and marijuana use and dependence could be traced to genetic factors.
“We found considerable overlap between the genes that contribute to marijuana dependencies and alcohol use and dependence,” said researcher Carolyn Sartor, Ph.D.
The study appears in the online edition of the journal Alcoholism: Clinical & Experimental Research.
