Marihuana

My teammate Juan Jose Sanz just told you about some effects that marijuana has on our health. Now, I will speak about the problems in daily life that smoking marijuanabrings. First of all, I want to tell you the addictive potential.
In long-terms, abusing of marijuana can lead to addiction; that is, compulsive drug seeking and abuse despitethe known of harmful effects upon functioning in the context of family, school, work, and recreational activities. Estimates from research of the National Institute on DrugAbuse suggest that about 9 percent of consumers become addicted to marijuana; this number increases among those who start young (about 17 percent) and among daily users (45percent aprox).
The most common sysmptoms for marijuana abusers are: irritability, sleeplessness, decreased appetite, anxiety, and drug craving, all of which can make itdifficult to remain abstinent. These symptoms begin within about 1 day following abstinence, the peak is at 2 or 3 days, and increase 1 or 2 weeks after the last time ofsmoking.
A number of studies have also shown a relation between chronic marijuana use and increased rates of anxiety, depression, and schizophrenia.
Researches clearlydemonstrate that marijuana has the potential to cause problems in daily life or make a person's existing problems worse. In one study from Citizens Against Legalizing Marijuana(CALM), heavy marijuana abusers reported that the drug impaired several important measures of life achievement, including physical and mental health, cognitive abilities, sociallife, and career status. Several studies associate workers' marijuana smoking with increased absences, tardiness, accidents, workers' compensation claims, and job turnover.
