State law ROCKS!
The defense does start with fighting the traffic ticket for being pulled over. States that have laws for 'driving under thc' is a bunch of bull. Depending on the State you may need a lawyer. States just want to cash in like the DUI laws. There is easy evidence to show that an every day user who is not under the influence would fail these THC driving laws.

Yes, the reason you need good grades in high school is because you need to go to a good college and then a good law school to be a successful high paid attorney. If one attends a not so great college or law school, it is very tough to get hired by a good firm that pays well. In LA, CA, a first year attorney can make anywhere from $50,000 to $185,000 ($165,000 + $20,000 or so bonus). To get the high paid job, one needs to get a job at biglaw and they only hire top students from top law schools.
If you don't have good grades, it will take longer to become a high paid attorney, but it can be done with a lot of hard work.
If one is a great salesperson (rainmaker) or has great connections (very wealthy family), one can make a good living if you can get the clients (very difficult). But often clients who pay a lot want to see where you went to school, etc, and they rather have an attorney who went to a top law school. When a lawfirm is trying to get a new client, they give them resumes of all the attorneys who will work on their case.
There are many types of business attorneys, for every type of business. Often they specialize, like entertainment, health care, insurance, employment, etc. For each type of business, some deal with contracts, some deal with litigation (lawsuits).
If you want to become an attorney, you will need to love to read and write. Even a trial attorney spends most of their days writing and reading. All day, for hours and hours. You will need a good understanding of literature, history and philosophy, because you must be able to write well and reference these subjects to make your writing interesting.
If your interested in becoming an attorney, spend some time interning or visiting a law office before you set it as your goal. It's a lot of work and much different than many people believe. Real attorneys get a good laugh at the attorney tv shows because they are soooo far from the reality!
