Will I pass the drug test I just took?

This morning, June 30, I took a surprise urine drug test for an important job. I am not a regular drug user but just spent 6 weeks in Europe and experimented like any 21-year-old would. The last time I smoked marijuana after 1-2 times per week use was May 16. I also tried speed on June 10 and cocaine on June 21. I'm told speed and cocaine won't be a problem since they leave the system so quickly, but is the fact that I smoked some pot six weeks ago going to cause me problems?
