Marijuana legalization

First I'll refute my opponents arguments If we legalize marijuana, we will likely see an increase of car crashes.Liberty does not necessarily equal good. Around 80 to 90 per cent of crime is related to alcohol and drug misuseCurrently Marijuana is linked to 1% of fatal car crashes {1}, while Alcohol is the reason for around 50% of fatal car crashes {3}. With my opponents reasoning we should make Alcohol illegal again, but why don't we it's because the United States has already gone down this path with Prohibition and the mob killed people and people still found ways to get alcohol in an unsafe way. This path sounds very similar with what the United States is going through right now with drug dealers giving it to people in an unsafe way, people still finding ways to get it and Gangs killing people like the mob, make it legal because he know the history {4}. Liberty is great like what Benjamin Franklin said "They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety."{2} My opponent is afraid that giving someone extra liberty will equal more death and crime, while the opposite would be true. Most crime related to Marijuana is because someone is smoking it, not actually doing anything that would hurt another. That 45,000 people die in the War against Marijuana {5} while no cases of someone dieing because directly in taking Marijuana {6}. So, In this case liberty does equal good.Many deaths caused by marijuana are actually reported as "accidents." Therefore, marijuana has actually killed people. Plus, your source points towards the death toll of the Mexican drug war,but then blames it on American drug banning.Accidents is not the fault of Marijuana, but the fault of people. Like someone can't blame the weapon for killing someone, or if the car merges and crashes, or if Marijuana was smoked and an accident happened, accidents are caused by people not non-living objects, because things can be prevented before the accident happens. War in Mexico is because of America drug banning. Most of the drug lords are fighting with each other trying to get into America to sell their drugs. If it becomes legal the drug lords will have to adapt to the supply and demand that happens in the United States. Because if it becomes legal it will become like a business much like the beer industry and safety and regulations will be put on it causing a safer product of the people who will already smoke it, compared to buying it from a shady character in a dark alley. The deaths will severely go down because no longer do the drug lords fight because it is illegal they have to compete with American companies in a legal way and it will be easier to find those who are bad because making it legal takes of the blanket of confusion.Is it fair to make such a dangerous drug, as dangerous as other drugs and kills to be legalIt is not dangerous like I stated earlier.{6}Cannabis can cause damage to the brain if taken before age 18.And its damage to the neurological system is still under discussion.Therefore it also harms mentally. If it becomes legal it will have restrictions on it like tobacco it can't be smoked before the age of 18. If someone wants to do damage to their brain that is their brain not mine, watching TV is not good for the brain or playing video games but no one is going to stop that and it shouldn't be stopped.{7} I have refuted by opponent's arguments and I have shown and explained that Marijuana unlike what my opponent is trying to allude to that it is some mega drug that will kill is false. Vote Pro and end the over stocked prisons, the unnecessary debt, and the restricted liberty.
