How was trade affected by the American Revolution? Tobacco was exported more during the years of 1767-1804, but then it started to decrease.

I still don't understand why tobacco exports was higher before the American Revolution and then dropped after it. Tobacco exports were higher before the American Revolution because the British passed laws? So the British took advantage of the cheap materials in America?

Years / Yearly Exports in Pounds
1767-1170 / 71 million
1771-1775 / 100 million
1790-1794 / 99 million
1795-1799 / 70 million

So after the American Revolution, tobacco export began to drop. The reason why it dropped is because the British had no more control over America after the Revolutionary War?
Could it have also been because of slavery? Tobacco was easy to grow back then and could basically grow anywhere. Before the American Revolution, slaves were still being traded. Tobacco was grown rapidly because of slavery, thus creating more exports? And after America gained its independence, after the American Revolution, they abolished slavery, which would explain why tobacco exports decrease over the years?
Is it possibly the taxes and the new tariffs on imported goods?

"During the war, it was tobacco exports that the fledgling government used to build up credits abroad. And, when the war was over, Americans turned to tobacco taxes to help repay the revolutionary war debt."
