How are Marijuana and Lethargy Related? – In short, yes, marijuana may make you lethargic. However, this is a temporary impact. One of the consequences of marijuana is a sensation of lethargy that sets in after 10 minutes of use. These effects often peak between one and three hours following the previous usage.
- Some individuals may experience effects for up to eight hours.
- Long-term marijuana usage may also result in lethargy, although this does not imply that your ability to function will be permanently affected.
- Studies indicate that short-term marijuana usage (through smoking, swallowing, sublingual administration, or tinctures) enhances dopamine production, resulting in euphoria.
This is why marijuana users report experiencing sensations of pleasure, well-being, and tranquility when under the influence. Dopamine is a hormone related with brain function control and motivation (reward). Long-term marijuana use, however, can change the brain’s reward system, resulting in a decrease in the brain’s natural dopamine production and a potential impact on the motivation levels of marijuana users.
- According to a research from University College London (UCL), persistent long-term marijuana usage might result in severe dopamine impairment.
- Individuals with cannabis dependency on the verge create less dopamine than non-users and even sociable users.
- The researchers believe that this decrease in dopamine may be the scientific reason for why cannabis users lose motivation over time and find it increasingly difficult to achieve their professional and educational objectives.
However, human studies are limited in their ability to determine the motivational levels of marijuana users. Nonetheless, the following are some of the long-term repercussions of marijuana abuse: Altered brain maturation, especially with younger users Cognitive impairment Depression Anxiety increased risk for schizophrenia Paranoia
Does smoking make you lazy?
New research published in Respirology reveals that smokers are less physically active, lack motivation, and are more prone to experience anxiety and depressive symptoms than nonsmokers. Dr. Karina Furlanetto of Universidade Estadual de Londrina, Brazil, conducted the first study to demonstrate that smokers are less physically active than nonsmokers.
- Sixty smokers and fifty non-smokers were required to wear pedometers for at least 12 hours every day over the course of six days.
- The data indicated that smokers walk less each day.
- When their ability to take deep breaths was evaluated, it was discovered that their lung function was diminished, which affected their ability to exercise.
When asked to estimate their personal health-related quality of life, smokers reported feeling more fatigued and lacked the drive to improve their sedentary habit. According to Dr. Furlanetto, this is the first study to reveal a reduction in the objectively assessed amount of physical activity in everyday life between adult smokers and nonsmokers.
In addition to lower lung function, exercise capacity, quality of life, and anxiety and depression symptoms, smokers walk less on a daily basis than nonsmokers.

Why Smokers Are Skinny Need a mid-afternoon snack? Taking a draw on a cigarette will certainly alleviate your appetite. In the United States and other industrialized nations, smoking is the leading avoidable cause of death, including lung cancer, heart disease, and chronic bronchitis.
- But smokers are, on average, skinnier than nonsmokers.
- New study explains how nicotine, the main element in cigarettes, suppresses hunger in the brain of smokers.
- In addition, the discovery identifies a potential therapeutic target for nicotine cessation and weight reduction.
- The nicotine receptor in the brain consists of 15 subunits, which may join in a variety of ways to generate receptors with distinct functions.
Nicotine may attach to each combination and initiate a cascade of unique actions, some of which result in the addictive features of cigarettes, others in a rise in blood pressure or a sense of relaxation. Scientists have long hypothesized that nicotine’s appetite-suppressing effects were mediated by reward- and behavior-reinforcing receptors.
- After all, both smokes and food are viewed as rewards by the brain.
- However, the latest research indicates that hunger has its own mechanism.
- Marina Picciotto, a behavioral neuroscientist at Yale University, set out to see whether activating a specific nicotine receptor, designated 34, had antidepressant benefits on mice.
But when Picciotto’s Yale colleague Yann Mineur, a behavioral neurogeneticist, was caring for the mice who had received medications designed to excite only 34 receptors, he observed an adverse effect: the animals were eating less. “Prior to this study, we did not believe that this sort of brain receptor would play such an important role in food intake,” Picciotto explains.
- She and Mineur went on to demonstrate that nicotine indeed bind to 34 receptors, which then transmit a signal to the remainder of the brain, signifying satiety.
- It is identical to the signal the brain transmits after consuming a huge meal.
- In the two hours following medication delivery, mice treated with a drug that binds to the 34 receptor consumed half as much food as untreated mice, the researchers reported online today in Science.
Since the weight gain associated with quitting smoking is typically a barrier for smokers, Picciotto proposes that medications may target the novel route to lower hunger during the first stages of smoking cessation. Additionally, such a medicine might have a wider application as an appetite suppressant to help in weight reduction, without the health risks associated with cigarette smoking.
In 1982, Neil Grunberg, a behavioral neuroscientist at the Uniformed Services University of the Health Sciences in Bethesda, Maryland, was the first to demonstrate that nicotine reduces hunger through tests on rats. According to him, the new study advances our knowledge of the phenomena he initially saw.
“The majority of individuals had accepted that the decrease in appetite was driven by a dopamine-reward pathway and left it at that,” explains Grunberg. Therefore, I believe that the most significant contribution of this article is the demonstration that nicotine operates via an additional channel.
- However, Grunberg cautions that the study only examines male mice.
- In his prior research, he discovered that the effects of nicotine on weight varies between men and women.
- According to him, women lose more weight when they begin smoking and gain more weight when they quit.
- Uncertainty remains as to whether this indicates that nicotine operates through an extra, hormone-regulated mechanism in the female brain.
Picciotto states that her team will repeat the research on female mice. “We’re still still attempting to answer our initial question,” she says. “Does this compound also have antidepressant properties?” * This page has been updated to reflect Yann Mineur’s actual title: Why Smokers Are Skinny
Does taking a shower diminish the high?
There is no scientific evidence to suggest that taking a shower would affect your high.
