I typically recommend that par value be set at $0.001 or $0.0001 per share. Thus, if a founder purchases 8,000,000 shares of common stock, the minimum price that the founder has to pay is $8,000 at $0.001 per share or $800 at $0.0001 per share.
Answer: Dextromethorphan (DXM) stays in your blood on average about 4 days. I repeat, that's on average. The range of days is around 3 - 5 if you are not being safe about it.
Benzodiazepines like Valium can stay in the system a pretty long time. It depends on how much you take and for how long. Also your health, age, weight and metabolic rate play a part. How long a drug stays in your system depends mainly on it's elimination half life. For Valium (diazepam) the initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of the active metabolite N-desmethyldiazepam is, on average, 100 hours.
