Marijuana is harmful, and let me tell you why. The tobacco industry successfully persuaded people for decades that the data linking smoking to cancer was false. The marijuana industry is facing the same problem that the tobacco industry faced years ago.
That problem has to do with data.
Does data prove that marijuana is harmful? Evidence proves that marijuana harms a person’s memory, and is addictive. Evidence also shows that marijuana may also cause cognitive impairment in kids. However, marijuana supporters say that this evidence is inconclusive.
