Before BYE, BEAM, and GRUENDER, Circuit Judges.
                           ___________

PER CURIAM.

       George Alan Lindsey pleaded guilty to possessing pseudoephedrine pills with
intent to use them to manufacture methamphetamine, in violation of 21 U.S.C.
§ 841(c)(2). He appeals his conviction claiming the district court1 erred in denying
his motion to suppress evidence. We affirm.

      On February 24, 2004, Officer Stephen Dudak of the Iowa State Patrol stopped
Lindsey on Highway 20 in Delaware County, Iowa, for speeding. Dudak asked

      1
        The Honorable Linda R. Reade, United States District Judge for the Northern
District of Iowa.
Lindsey to step out of his vehicle after observing a chemical odor wafting from the car
and three eyeglasses cases in the passenger seat. He also noticed Lindsey's eyes were
glassy and his pupils appeared small. Lindsey answered all of Dudak's questions
without difficulty and denied possessing firearms or controlled substances. When
asked whether Lindsey possessed methamphetamine, he appeared nervous but
responded "no." Dudak then asked if he could search Lindsey's vehicle. Lindsey gave
both oral and written consent, but noted he was embarrassed by "dirty" magazines in
the car.

       During the search, Dudak found methamphetamine, a butane lighter, and a drug
pipe in one of the eyeglasses cases. He placed Lindsey under arrest. Once Lindsey
arrived at the sheriff's office, he was read his rights under Miranda v. Arizona, 

(1966). Lindsey then admitted his involvement in the manufacture of
methamphetamine. A urine sample was collected, which tested positive for
methamphetamine. An inventory search of Lindsey's vehicle uncovered 660
pseudoephedrine pills, starter fluid, lithium batteries, and other items used to
manufacture methamphetamine. Lindsey moved to suppress the evidence, but the
district court denied the motion on the grounds Dudak had probable cause and
Lindsey gave consent.

       We review the district court's "conclusions of law regarding a motion to
suppress de novo and its fact findings for clear error." United States v. Sanders, 

, 773 (8th Cir. 2005) (citing United States v. Booker, 

, 931 (8th
Cir. 2001)).

       Under the Fourth Amendment, searches "conducted without a warrant are per
se unreasonable, subject to a few well-established exceptions." United States v.
Kennedy, 

, 1140 (8th Cir. 2005). Under the "automobile exception,"
an officer can "search a vehicle without a warrant if [he has] probable cause to believe
the vehicle contains evidence of criminal activity." United States v. Hill, 386 F.3d

                                          -2-
855, 858 (8th Cir. 2004) (citing Coolidge v. New Hampshire, 

, 455
(1971)). In this case, the district court found probable cause because of odors of
marijuana and other chemicals from Lindsey's vehicle, Lindsey's glassy eyes and
small pupils, the presence of multiple eyeglasses cases on the passenger seat of
Lindsey's automobile, and Lindsey's nervous behavior when asked about
methamphetamine. We have previously upheld warrantless searches based, in part,
on suspicious odors emanating from a suspect's automobile. See, e.g., United States
v. Gerard, 

, 489 (8th Cir. 2004) (noting odor of illegal drugs can be
"highly probative in establishing probable cause for a search"). Viewing the totality
of the evidence, see United States v. Caves, 

, 90 (8th Cir. 1989), the
district court did not err.

       Additionally, the district court found Lindsay gave valid consent to the search
of his vehicle. Consent must be given knowingly and voluntarily, and the finding of
consent is a matter of fact reviewed for clear error. 

(citing
United States v. Lee, 

, 834 (8th Cir. 2003)). "The test applied to
determine if consent is free and voluntary is whether, in light of the totality of the
circumstances, consent was given without coercion, express or implied." 

v. Bustamonte, 

, 227 (1973)).

       The record shows Lindsey was forty-one at the time of the incident, possessed
a graduate equivalency degree, and had a not insignificant criminal history. Although
he may have been under the influence of drugs at the time he gave consent, there is
no evidence of coercion or improper police tactics. United States v. Gipp, 

, 686 (8th Cir. 1998). The "mere fact that one has taken drugs, or is intoxicated,
or mentally agitated, does not render consent involuntary." United States v. Rambo,

, 1297 (8th Cir. 1986). In fact, Lindsey was capable of answering
Dudak's questions and even stated he was embarrassed about the "dirty" magazines
in his vehicle. Although Miranda warnings were not administered until after the
search was completed, this, too, does not render Lindsey's consent involuntary. See

                                         -3-
United States v. Fleck, 

, 892 (8th Cir. 2005). Under the totality of the
circumstances, the district court did not clearly err in denying the motion to suppress.

       Because the district court did not err in denying Lindsey's motion to suppress
the evidence, his later admissions are not "fruit of the poisonous tree." Accordingly,
we affirm.
