Can #UK#academics explain these spammy emails from publication agencies who want to feature my academic articles? I've been told this this a scam, but I'm not sure how -- do they charge money to do this? Is this related to the dreaded #REF?
As far as I'm concerned, if some publication wants to write a feature based on one of my publications... go for it. You don't need to contact me about it.
Be careful with your concept of physically versus psychologically addicted, it’s not really a 100% seperatable dichotomy like that. Your brain is your brain after all, whether you decide to call something physical or psychological it’s all happening inside the brain. I think because cannabis doesn’t tend to have severe withdrawal effects (like alcohol withdrawal, which can kill you) people assume that means they’re not dependent or that it doesn’t have direct effects on the reward processing centers in the brain to reinforce its use again in the future. That’s what distinguishes addictive drugs from things that are just generally pleasant so we want to do them again, they have a direct chemical interaction with the neural circuits that are supposed to be helping decide if a behavior should be done again or not. Kind of tipping the scales in their favor, making you want to do something again more so than just the pleasentness of the past experience alone would otherwise do. You’re going to have an easier time quitting carrots than you will cannabis, even if you find them both equally pleasant in the moment.
Don’t get me wrong though, cannabis is waaaay less addictive than things like nicotine or alcohol, and has far less harmful effects than those. I think there is a tendency (especially with things like DARE lying about drug dangers when people were younger) to over correct and say things like it’s a miracle drug that’s non addicting and can never harm you and can fix everything wrong in your life! I’m for recreational cannabis legalization, but people should understand it’s actual risks, even though they are much less than other recreational drugs.
The cumulative probability estimate of transition to dependence was 67.5% for nicotine users, 22.7% for alcohol users, 20.9% for cocaine users, and 8.9% for cannabis users. Half of the cases of dependence on nicotine, alcohol, cannabis and cocaine were observed approximately 27, 13, 5 and 4 years after use onset, respectively.
Cannabis-derived psychoactive compounds such as Δ9-tetrahydrocannabinol and synthetic cannabinoids directly interact with the reward system and thereby have addictive properties. Cannabinoids induce their reinforcing properties by an increase in tonic dopamine levels through a cannabinoid type 1 (CB1) receptor–dependent mechanism within the ventral tegmental area. Cues that are conditioned to cannabis smoking can induce drug-seeking responses (ie, craving) by eliciting phasic dopamine events.
